摘要：

Intramolecular triplet-triplet (T-T) energy transfer in a series of polymethylene chains having a carbazole group as an energy donor and a naphthalene group as an energy acceptor has been studied by phosphrescence measurement. The phosphorescence decay curves were analyzed by Dexter's equation in which the distribution of donor-acceptor (D-A) distance was calculated by the conformational energy analysis. The results of the simulation were in fairly good agreement with the experimentally observed decay curves. We conclude that the through-space mechanism is adequate for intramolecular T-T energy transfer of the flexible D-A molecules.
