We have prepared poly[2-(2'-ethylhexyloxy)-5-phenylethynyl-1,4- phenylenevinylene] (PAPPV) 13 via, S-methyl xanthate 10, chloro 11, and O- ethyl xanthate 12 precursor polymers. All three precursor polymers could be thermally converted to give films of 13. We found that the UV-VIS and photoluminescence (PL) spectra, and PL quantum yields (11-14%) were similar when 13 was prepared from either the S-methyl xanthate or chloro precursor polymers. In contrast, the UV-VIS and PL spectra of 13 prepared via the O- ethyl xanthate precursor polymer were observed to be blue-shifted and the PL quantum yield was much lower (2%).
