Abstract

A novel C₇₀ fullerene derivative ICBM was rationally designed and synthesized by [4+2] cyclic addition reaction between an indene derivative (methyl 4-(1H-inden-3-yl)butanoate) and C₇₀. The absorption and photoluminescence of the mixed films of ICBM with different polymer donor materials were characterized. The electrochemical reduction behavior of ICBM in the range of 0 to -2.5 V was investigated by the cyclic voltammetry method, and the result shows that the lowest unoccupied molecular orbital (LUMO) level of ICBM is 0.07 eV higher than that of PC₇₀BM. The photovoltaic devices based on poly (3-hexylthiophene) (P3HT) and a low band gap polymer (PTB7) as donors, with ICBM as an acceptor gave power conversion efficiencies of 5.00% and 6.67%, respectively. The result demonstrates that this novel C₇₀ fullerene derivative is a much better acceptor for wide-band gap as well as low-band gap donor polymers in the BHJ polymer photovoltaics.
