Synthesis and characterization of thienyl‐substituted methanofullerene dyads

Abstract

Two derivatives of methano[60]fullerene derivatives based on cyclopenta[c]thiophene were prepared as the precursors for polythiophene with fullerene side chains, and were fully characterized by NMR and MALDI TOF, the photo‐electric and spectral properties were investigated through the analysis of UV and cyclic voltammetry. Meanwhile, the mono‐adduct was applied as electron acceptor for bulk‐heterojunction solar cell, which exhibited the power conversion efficiency of 0.5%. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1433–1437, 2018
