Polymer semiconductor devices are light weight, low cost, low temperature processing and flexible. Research on semiconductor polymers has attracted attention recently. Hemi-isoindigo has relatively simple structure and is easy to synthesize. The new polymers based on it have achieved high performance in polymer solar devices. Two series of hemi-indigoid monomers, selenophen based hemi-isoindigo and hemi-trichochrome have been proposed in this plan. The Yamamoto coupling reaction will be used for the polymerization of the new monomers to obtain regio-random polymers. New reagent Knochel-Hauser base will be used for selective hydrogen/metal exchange on new monomers, followed by Kumada-Tamao cross-coupling polymerization to achieve regio-regular polymers. The effect of molecular structure and dipole moment of the polymers on aggregated states, dynamic processes and device performances will be studied. The new monomers proposed in this plan could become a class of important and useful building blocks for high-performance semiconducting polymers.
