Abstract
Novel organometallic conjugated polymer containing (η 6-arene)Cr(CO) 3 and platinum in the main chain was synthesized by dehydrohalogenation coupling reaction of (η 6-1,4-diethynylbenzene)tricarbonylchromium with trans-(PBu 3) 2PtCl 2. The polymer was soluble in common organic solvents and has the number-average molecular weight of 31,000 by GPC analysis. The polymer exhibited an absorption peak derived from π–π ∗ interaction at 358 nm in the UV–Vis spectrum, which showed a red shift of approximately 90 nm compared to that of the model compound. The photochemical ligand exchange reaction of the polymer was also investigated.
