Energy transfer in polymers—VII

摘要: Abstract The efficiency of triplet energy transfer from the benzophenone group to naphthalene has been studied in a series copolymers styrene-vinylbenzophenone, either as films or glassy solutions at 77 K. Energy migration shown be efficient both cases. For given copolymer, Hirayama's critical distance is larger than solutions. In cases, it decreases with decreasing vinylbenzophenone content. number jumps between identical molecules during life-time excited state calculated according hopping model and Voltz theory on migration. results show that these solid polymers not consequence exchange interactions exponentially mean chromophores. Organized regions, characterized by higher transfer, have taken into account.
