The photolysis of covalently linked N-alkyl picolinium phenylacetate-carbazole dyads was analyzed experimentally and by using density functional theory (DFT) and time dependent-DFT (TD-DFT) calculations. In contrast to earlier observations efficient one and two-photon fragmentations conditions were found for 15 c (δ =0.16 GM at 730 nm) opening the way for the design of a novel class of "caged" compounds.
实验和密度泛函理论（DFT）和含时密度泛函理论（TD-DFT）计算分析了共价连接的 N-烷基吡啶翁苯基醋酸盐-咔唑偶联物的光解。与早期的观察结果相反，对于 15c（在 730nm 时为 0.16GM 的 δ 值），发现了有效的单光子和双光子断裂条件，为设计新型“笼状”化合物开辟了道路。
