✦ Synopsis

Abstract

Summary: A novel copolymer containing perylene bisimide and porphyrin units was synthesized through a Wittig‐type coupling reaction and characterized. An electrochemical experiment showed its electronic properties. Optoelectronic measurements showed a steady and rapid cathodic photocurrent response of the polymer film. The features of copolymer colloids were also studied by UV‐Vis spectrometry and TEM. A large quantity of nanoparticles were observed with TEM, with a mean diameter of 200 nm. The size effect leads the absorption wavelength of the nanoparticles to be red‐shifted, which is consistent with the results of UV‐Vis spectrometry.
