Unlike the highly symmetric <a href=\"https:\/\/www.thefullerene.com\/about-fullerene\/what-is-fullerene-c60\/\">C60 fullerene<\/a> (which has Ih symmetry and resembles a soccer ball), the geometric shape of the C70 molecule appears as an elongated ellipsoid, often vividly described as a &#8220;rugby ball&#8221; or &#8220;olive-shaped&#8221; structure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"reduction-in-symmetry-and-electronic-structure-alienation\"><strong>Reduction in Symmetry and Electronic Structure Alienation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The symmetry of the C70 molecule belongs to the D5h point group. From the perspective of structural evolution, C70 can be viewed as inserting a ring of 5 hexagons at the equatorial position of <a href=\"https:\/\/www.thefullerene.com\/about-fullerene\/what-is-fullerene-c60\/\">C60<\/a>, thereby elongating the molecule along the five-fold axis. This reduction in symmetry from Ih to D5h has a profound impact on the electronic energy levels of the molecule. In <a href=\"https:\/\/www.thefullerene.com\/about-fullerene\/what-is-fullerene-c60\/\">C60<\/a>, due to its high symmetry, many electronic transitions are quantum mechanically forbidden, whereas the reduction in symmetry in C70 allows transitions that were forbidden in C60 to become permitted in C70, which directly leads to C70 having a stronger absorption capability in the visible light range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to quantum chemical calculations and experimental observations, there are five groups of non-equivalent carbon atoms in the C70 molecule, which makes its chemical environment more complex than that of C60. The bond length distribution of the molecule is no longer uniform but has eight different bond lengths, ranging between 0.137 nanometers and 0.146 nanometers. Generally, the 6:6 bonds shared by hexagons have stronger double bond characteristics and shorter bond lengths; while the 6:5 bonds shared by hexagons and pentagons are closer to single bonds and have longer bond lengths.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"hybrid-orbitals-and-conjugated-system\"><strong>Hybrid Orbitals and Conjugated System<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The carbon atoms in C70 are all in the sp2 hybridization state, and each carbon atom forms covalent bonds with three adjacent carbon atoms. However, due to the curvature of the spherical or ellipsoidal shape, these sp2 hybrid orbitals are not completely planar but carry a certain degree of sp3 character, and this &#8220;pyramidalization&#8221; enhances the reactivity of the molecule. Although the all-carbon skeleton forms a massive $\\pi$-electron conjugated system, C70 does not exhibit &#8220;superaromaticity&#8221; in the traditional sense, as it tends to avoid forming double bonds in the five-membered rings, resulting in limited electron delocalization. This electron-deficient characteristic makes C70 behave like an electrophilic alkene, highly prone to addition reactions with electron-rich substances.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Structural Parameter<\/strong><\/td><td><strong>C60 Fullerene<\/strong><\/td><td><strong>C70 Fullerene<\/strong><\/td><\/tr><\/thead><tbody><tr><td>Number of Carbon Atoms<\/td><td>60<\/td><td>70<\/td><\/tr><tr><td>Molecular Shape<\/td><td>Spherical (Soccer ball-like)<\/td><td>Ellipsoidal (Rugby ball-like)<\/td><\/tr><tr><td>Symmetry Point Group<\/td><td>Ih<\/td><td>D5h<\/td><\/tr><tr><td>Number of Hexagons<\/td><td>20<\/td><td>25<\/td><\/tr><tr><td>Number of Pentagons<\/td><td>12<\/td><td>12<\/td><\/tr><tr><td>Groups of Equivalent Carbon Atoms<\/td><td>1<\/td><td>5<\/td><\/tr><tr><td>van der Waals Diameter<\/td><td>Approx. 1.1 nm<\/td><td>Approx. 0.71 nm \u00d7 0.79 nm<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Data Source: Comprehensive study on the molecular symmetry and physical properties of fullerenes.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"comparative-analysis-of-c70-and-c60-fullerenes-and-optoelectronic-advantages\"><strong>Comparative Analysis of C70 and C60 Fullerenes and Optoelectronic Advantages<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the market for wholesale C70 fullerene, customers frequently need to compare the performance differences between C60 and C70 to determine material selection for specific applications. Although C60 currently occupies the majority of the market share due to its lower production cost and earlier research, C70 exhibits irreplaceable advantages in high-performance optoelectronics and biomedical fields.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"a-leap-in-visible-light-absorption-capability\"><strong>A Leap in Visible Light Absorption Capability<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The most prominent physical advantage of C70 lies in its broad-spectrum absorption characteristics. Studies indicate that in aqueous dispersions (nC70), the total integrated absorbance of C70 in the visible light range of 400 nm to 800 nm is 2.3 times that of C60. In the solution state, C60 appears purplish-red or light brown, while C70 exhibits a dark reddish-brown color, which intuitively reflects its stronger light-capturing ability in the visible spectrum.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This absorption advantage primarily stems from the reduction in symmetry. In C60, due to its Ih symmetry, the lowest energy electronic transitions are forbidden, resulting in extremely low absorption coefficients in the visible light region. The D5h symmetry of C70 allows for more dipole moment transitions, thereby enhancing its absorption in the long-wavelength band. For organic photovoltaics (OPV), this means that using C70 derivatives as acceptor materials can significantly increase the short-circuit current density (Jsc), thereby improving the overall power conversion efficiency.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"exciton-dynamics-and-triplet-state-lifetime\"><strong>Exciton Dynamics and Triplet State Lifetime<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The performance of C70 in the excited state is equally superior to that of C60. C70 has a long-lived triplet excited state (approximately 120 microseconds in benzene solution), and its quantum yield for generating singlet oxygen (1O2) is extremely high ($\\Phi = 0.81 \\pm 0.15$). More importantly, in the aggregated state, C60 excitons often lose activity due to rapid intermolecular quenching, whereas the triplet state lifetime of C70 in nano-aggregates (nC70) is about 100 times longer than that of C60. This characteristic gives C70 stronger energy conversion efficiency and biological activity in photocatalysis and photodynamic therapy (PDT).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"fine-tuning-of-solubility-and-reactivity\"><strong>Fine-tuning of Solubility and Reactivity<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In terms of chemical reactivity, because C70 has five groups of non-equivalent carbon atoms, the selectivity of its reaction sites is more complex than that of C60. C70 possesses higher electron affinity, making it more active in certain redox reactions. Regarding solubility, C70 exhibits good solubility in aromatic solvents such as toluene, carbon disulfide, and xylene; although slightly lower than C60, it presents no significant obstacles in actual industrial processing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"core-application-in-organic-photovoltaics-opv-pc71bm-and-beyond\"><strong>Core Application in Organic Photovoltaics (OPV): PC71BM and Beyond<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the energy sector, the application of C70 and its derivatives is the key driving force pushing organic photovoltaic technology towards commercialization. The most successful example is [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM), which has become the standard acceptor material for developing high-efficiency solar cells in laboratories and industries worldwide.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"evolution-from-pc61bm-to-pc71bm\"><strong>Evolution from PC61BM to PC71BM<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Early OPV research primarily used the C60 derivative PC61BM, but limited by the weaker visible light absorption of C60, cell efficiency was difficult to break through. The introduction of PC71BM changed this situation. Because the C70 skeleton enhances light absorption, PC71BM can effectively compensate for the shortcomings of donor materials in the absorption spectrum, significantly increasing the photocurrent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In high-performance ternary blend systems, PC71BM is often added as a third component to optimize the morphology of the active layer. For example, in systems based on PTB7-Th and the non-fullerene acceptor Y6, the introduction of an appropriate amount of PC71BM can significantly improve the charge transport pathways, increasing the fill factor (FF) and power conversion efficiency (PCE) of the device. Research records show that the efficiency of optimized ternary cells can stably exceed 17%, and even reach above 18.2% in some cutting-edge studies.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Photovoltaic Parameter<\/strong><\/td><td><strong>Pure Non-Fullerene System (PM6:Y6)<\/strong><\/td><td><strong>Fullerene-Doped Ternary System (PM6:Y6:PC71BM)<\/strong><\/td><\/tr><\/thead><tbody><tr><td>Average Power Conversion Efficiency (PCE)<\/td><td>15.5% &#8211; 16.5%<\/td><td>17% &#8211; 18.2%<\/td><\/tr><tr><td>Short-Circuit Current Density (Jsc)<\/td><td>Approx. 24 mA\/cm\u00b2<\/td><td>&gt; 26 mA\/cm\u00b2<\/td><\/tr><tr><td>Stability (Thermal\/Light)<\/td><td>General<\/td><td>Significantly Enhanced<\/td><\/tr><tr><td>Morphology Control<\/td><td>More Difficult<\/td><td>Easier (PC71BM acts as a regulator)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Data synthesized from studies on the performance of PC71BM in organic solar cells.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Carbonsphere, as a leading global supplier of nanomaterials, is deeply aware of the decisive impact of PC71BM purity on battery performance. To support the global green energy transition, Carbonsphere provides electronic-grade high-purity C70 (purity $\\ge 99.9\\%$), ensuring that downstream synthesized PC71BM has extremely low metal impurities and stray isomer content, thereby improving device reproducibility and lifespan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"biomedicine-and-broad-health-the-fullerene-revolution-led-by-healthyking\"><strong>Biomedicine and Broad Health: The Fullerene Revolution Led by Healthyking<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond its outstanding performance in hard-core electronics, the potential of C70 fullerene in the biomedical field is being deeply explored.

How does the molecular structure of C70 fullerene affect its optoelectronic properties?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The D5h symmetry of C70 is lower than the Ih symmetry of C60, which breaks the forbidden restrictions of many electronic transitions, making its absorbance in the visible light region (400-800nm) 2.3 times higher than that of C60. This makes it a more efficient electron acceptor in organic solar cells.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Why is PC71BM more popular than PC61BM in solar cells?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PC71BM is based on the C70 skeleton and has a broader visible light absorption range. In battery devices, this means it can capture more light energy and convert it into current, usually resulting in a higher short-circuit current density (Jsc) than PC61BM.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Is C70 fullerene safe in biomedical applications?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pure C70 is insoluble in water and is usually used in functionalized forms (such as fullerenol). The 99.95% high-purity fullerene provided by Healthyking eliminates the risk of heavy metals and residual solvents, showing good biocompatibility in neuroprotection and skin antioxidation research.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4.
