摘要：

The packing structure, thermal properties, and photophysical and electrochemical properties are presented. Some soluble benzodipyrrolidone-based small molecules were synthesized, and the first two benzodipyrrolidone- based polymers were prepared by means of Suzuki coupling reactions. The UV vis absorption and spectra of benzodipyrrolidone-based small molecules and polymers were recorded in chloroform at a concentration of 10-5 M and in spincoated thin film. The low band gaps indicate benzodipyrrolidone should be an effective unit for constructing low-bandgap polymers. The photoluminescence spectra of the small molecules and the polymers were also recorded in chloroform at a concentration of 10-5M. The basic properties such as packing structure, UV absorption, and electrochemical oxidation and reduction were demonstrated.
