摘要：

Optical absorption and photoluminescence measurements on the title polymers, [Pt(PBu3n)2-(C = C)m-C = C]n (m = 1, 2) show that there is appreciable pi-electron conjugation extending through the metal sites on the chain, with a lower pi-pi* energy gap for the triacetylenic than for the diacetylenic compound.
