3',3''-Diphenyl-3'H,3''H-dicyclopropa[1,9:52,60][5,6]fullerene-C60-Ih-3',3''-dibutanoic acid 3',3''-dimethyl ester serves as an indispensable, ultra-pure functionalized fullerene bisadduct derivative, benchmark n-type organic semiconductor electron acceptor with elevated LUMO levels, and versatile interfacial passivation material extensively utilized across polymer organic photovoltaics (OPV), inverted perovskite solar cells (PSCs), broadband organic photodetectors, organic thin-film transistors (OTFTs), and flexible printed electronics sectors. In organic semiconductor physics and advanced photovoltaic device engineering, universally recognized as Bis-PC61BM, Bis-PCBM, or Bis-[60]PCBM, its molecular architecture incorporates two solubilizing phenyl-butyric acid methyl ester cyclopropane moieties covalently grafted onto a single spherical C60 fullerene core; this dual functionalization moderately contracts the extended pi-conjugated network of the fullerene cage, driving its lowest unoccupied molecular orbital (LUMO) energy level up by approximately 0.15 eV relative to the benchmark mono-adduct PC61BM; when blended with conjugated donor polymers such as P3HT within bulk-heterojunction (BHJ) active layers, this elevated LUMO level substantially expands the electrochemical bandgap between donor HOMO and acceptor LUMO, propelling the open-circuit voltage (Voc) from 0.6 V to beyond 0.73-0.75 V, thereby delivering a notable surge in device power conversion efficiency (PCE); furthermore, the two pendant aliphatic ester chains disrupt self-crystallization tendencies, conferring superior thermodynamic solubility and solution processability in aromatic solvents such as chlorobenzene, o-dichlorobenzene, and toluene, which effectively suppresses macroscopic domain agglomeration to establish ideal nanoscale interpenetrating bicontinuous networks that ensure efficient sub-picosecond charge generation with minimal bimolecular recombination. In inverted (p-i-n) planar heterojunction perovskite solar cells, it is deployed as an electron-transporting and defect-passivating layer; its tailored LUMO level establishes a barrier-free energetic cascading alignment with the perovskite conduction band, minimizing interfacial energy dissipation, while its multivalent polar ester handles and pi-electron clouds coordinatively interact with undercoordinated surface lead ions and halide vacancies across perovskite grain boundaries, effectively quenching non-radiative trap states, reducing hysteresis, and enhancing long-term operational photothermal durability. In broad-spectrum organic photodiodes and optical sensors, it suppresses leakage currents to maximize detectivity and signal-to-noise performance. Furthermore, in organic field-effect transistors, functional antistatic polymer composites, and specialized optoelectronic monitoring probes for petroleum and natural gas infrastructure, chemical systems engineered from 3',3''-Diphenyl-3'H,3''H-dicyclopropa[1,9:52,60][5,6]fullerene-C60-Ih-3',3''-dibutanoic acid 3',3''-dimethyl ester deliver outstanding electronic tunability, reproducible thin-film reliability, and broad multi-industry value.
