Photocurrent generation properties of electrochemically polymerized terthiophene-linked fullerene film

Terthiophene derivative of C60 fullerene was synthesized. The polymerized film of this fullerene analog was prepared on an indium–tin-oxide electrode by electrochemical polymerization at +1.4 V versus a Ag wire. The absorbance of the polymerized film was increased by increasing the electrochemical polymerization time. The polymerized film generated stable photocurrents in the presence of triethanolamine. Optimization of the amount of adsorbed polymerized film for improving the photoelectric conversion performance was achieved by controlling the polymerization time.
