摘要

本文综述了本实验室在刚性有机溶液中溶质激发态辐射分解形成和失活的研究结果。从基质到溶质分子的能量传递被证明发生在这些体系中。在芳香族分子(甲苯,聚苯乙烯)形成的基质中,这种能量传递是通过激发能的单线态-单线态和三重态-三重态转移过程实现的。发现并讨论了三重态猝灭的三个过程:(i)电子激发能向溶剂自由基转移;(ii)溶质三重态分子与溶质三重态分子相互作用时溶剂分子激发的湮灭;(iii)溶质三重态分子被溶剂辐射产物特异性失活。

Triplet states in radiolysis of solid solutions

Results of studies carried out in this laboratory on radiolytic formation and deactivation of solute excited triplet states in rigid organic solutions are reviewed. Energy transport from matrix to solute molecules was shown to occur in these systems. In matrices formed by aromatic molecules (toluene, polystyrene) this energy transport is realized via processes of singlet-singlet and triplet-triplet transfer of excitation energy. Three processes of triplet quenching have been found and discussed: (i) transfer of electronic excitation energy to solvent radicals, (ii) annihilation of solvent molecular excitations upon interaction with solute triplet molecules and (iii) specific deactivation of solute triplet molecules by solvent radiation products.
