| Abstract: | A cationic poly(p-phenylene vinylene) related copolymer without bulky phenylene substitutents attached to the conjugated backbone was prepared through Wittig reaction. The molecular structure and optical properties were highly investigated through 1H-NMR, UV and PL spectroscopy. The quenching behavior was also investigated, and the results demonstrate that incomplete quenching exists, which is consistent with the cationic poly(p-phenylene vinylene) related copolymer containing bulky phenylene substitutents, probably correlated with the conformation of conjugated backbone and intermolecular aggregation. |
