  量子放大异构化：高分子光学材料的新概念1

  摘要：

  在称为量子放大异构化（QAI）的过程的基础上描述了新型光敏聚合物的制备和评估。QAI工艺在聚合物介质中利用了光引发的阳离子自由基异构化化学反应。描述了两类材料：一种是QAI反应物分子掺杂在聚合物基质中，另一种是反应物是功能化聚合物的一部分。量子产率实验表明，异构化反应可以通过链式工艺以中等效率进行。光化学转化实验表明，QAI反应物的高度转化是可能的。转化率和程度与聚合物的玻璃化转变温度密切相关。对于分子掺杂的聚合物，检验并排除了基于反应物的扩散或相分离来解释高转化率的假说。讨论了模型以合理化影响量子产率和光化学转化的实验因素。

  Photosensitized [2+2] cycloreversion reactions of arylated cage compounds in nonpolar solvents. Highly efficient adiabatic exciplex isomerization

  摘要：

  Photosensitized [2+2] cycloreversion reactions of arylated cage compounds 1 to dienes 2 using several cyanoaromatics as sensitizers are reported. In acetonitrile, 1a isomerized to 2a via an efficient cation-radical chain process. In contrast, the isomerization of 1a to 2a proceeded via an exciplex in benzene. Interestingly, the exciplex emission maximum observed in the fluorescence quenching by 1a was the same as that by 2a. Such a coincidence was also observed in a series of arylated cage compounds 1a-d and dienes 2a-d in various solvents. These observations together with the results obtained from reaction and exciplex emission quenching experiments clearly demonstrated the occurrence of adiabatic exciplex isomerization of 1 to 2. Efficiencies (A(e)) of the adiabatic process obtained by comparing the intensities of the observed exciplex emissions with those of diene exciplex emissions were quite high and became almost quantitative in some cases. A(e) values were found to increase as (1) the oxidation potentials (E1/2ox) of cage compounds 1a-d decreased, (2) the reduction potentials (E1/2red) of sensitizers increased, and (3) the solvent polarity (E(T)) increased.
