The substituents located in para, meta and ortho-position of the benzenoid ring involve a large range of delta-pi electron-donor-acceptor capability. Theoretical analysis shows that the optical property is affected by the steric and electronic characteristics of the substituents on the benzenoid ring, moreover, the third-order polarizability regularly varies with the polymerization degrees.展开更多
