Abstract

We have prepared poly[2-(2′-ethylhexyloxy)-5-phenylethynyl-1,4-phenylenevinylene] (PAPPV) 13via, 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%).
