Large Photocurrent Generation of Gold Electrodes Modified with [60]Fullerene-Linked Oligothiophenes Bearing a Tripodal Rigid Anchor

Abstract

[60]Fullerene-linked quarter- and octithiophenes bearing a tripodal rigid anchor have been synthesized as components of highly efficient SAM-based photovoltaic cells. It has been demonstrated that the tripodal anchor plays an important role in preparing a well-organized SAM on a gold electrode, leading to marked enhancement of the photocurrent generation as compared to the reference system with a one-armed anchor.
