摘要：

The synthesis and optical properties of novel electron donor-acceptor type PPVBs with various side groups, and the detailed investigation on the photooxidative stability of their PPVB has been reported. Number-average molecular weight (Mn) and molecular weight distribution [weight-average molecular weight/number-average molecular weight (Mw/Mn)] values of all polymers were estimated by size exclusion chromatography (SEC). The photostabilities of the polymers were examined by monitoring decrease of the PL spectra under continuous UV irradiation using a UV lamp under aerobic conditions. Their stabilities should be responsible for electron density of the substituents in the comonomers except for comonomer having trifluoromethyl group. The n-type organoboron polymers, poly (p-phenylenevinylene-borane)s (PPVBs), including boron atoms in the polymer backbone by hydroboration polymerization of tripylborane and diyne monomers has been synthesized.
