摘要: 10,12-Pentacosadiynoic acid (DA) hybrid films with various loadings of a ruthenium(II) complex ([Ru(dpphen)3]Cl2) (0.5 to 4.6 mol%) were prepared by spin-coating. Solid-state polymerization diacetylene monomers can be sensitized in the visible light region embedding [Ru(dpphen)3]Cl2 into films. In situ absorption measurement enables us study kinetics DA The process described first order rate equation and constants are determined discussed detail. mechanism sensitization is discussed, an explanation based on photo-induced electron transfer from[Ru(dpphen)3]Cl2 moiety presented. Strong quenching fluorescence was observed even at low monomer conversion. Enhancement polydiacetylene (PDA) could presence [Ru(dpphen)3]Cl2. energy migration from molecules polymer chains also
