Abstract

We have prepared poly[2-(2'-ethylhexyloxy)-5-phenylethynyl-1,4-phenylenevinylene] (PAPPV) via, S-methyl xanthate, chloro, and O-ethyl xanthate precursor polymers. All three precursor polymers could be thermally converted to give films of . We found that the UV-VIS and photoluminescence (PL) spectra, and PL quantum yields (11-14%) were similar when was prepared from either the S-methyl xanthate or chloro precursor polymers. In contrast, the UV-VIS and PL spectra of prepared via the O-ethyl xanthate precursor polymer were observed to be blue-shifted and the PL quantum yield was much lower (2%).
