摘要：
The following photophysical properties related to the lowest triplet of poly(2-vinylnaphthalene) (P2VN) have been investigated by laser flash photolysis and pulse radiolysis: Tn ← T1 absorption spectrum, lifetime, extinction coefficient ε{lunate}T, quantum yield of formation φTM and triplet energy transfer rate constant kQ in reaction between the biphenyl lowest triplet and P2VN. It has been found from studies of four polymers with varying degrees of polymerization (P = 109, 318, 688, and 2690) that φTM and kQ become smaller the higher the degree of polymerization. © 1979.
