We use AOT/iso-octane/water reverse micelles as a biological model to mimic the properties of triplet-excited-state porphyrin in the interfacial region. The amphiphilic property of compound is difficult to evaluate for different system.

用AOT／异辛烷／水反相胶束体系营造了一个多相、多界面的环境，通过对卟啉化合物三重态寿命的测量，研究了以亲水基团为端基的具有不同侧链链长的两亲卟啉化合物的界面行为，探讨了卟啉化合物的亲水疏水性质与界面环境间的相互作用，这对卟啉类光疗药物的结构优化具有帮助。

It has been demonstrated that appreciable photoinduced intramolecular electron transfer took place giving long-living redox-ion intermediates via a triplet pathway.

发现其中一些化合物在极性溶剂中受光激发后，通过快速的电子转移生成较长寿命的电荷分离中间体，得到十分有意义的结果。

He is the one who destroyed Virtus with a triplet in the first derby; Sante also scored against Napoli, Perugia, Firenze, Palermo.

The codons are indicated as triplet groups of yellow-brown bases.

密码子用有黄色基部的三联体表示。

Fluorescence emission spectra and UV absorb spectra analysis have been undertaken to test the influence of solvent polarity on the lowest excited singlet state of the tertiary amines. The absorption maxima were red-shafted slightly, and the emission maxima were red-shafted strongly, which showed all of the three compounds were found to be essentiallyππ* in character, which makes for the formation of triplet-exciplex state and the subsequent reactions,?known as photo-reduction and hydrogen-abstraction.

本文借助光谱检测的手段测试了新合成的增感剂的光物理化学性能，利用荧光发射光谱和紫外吸收光谱测试了溶剂极性对叔胺的最低激发单重态的影响，实验结果表明叔胺的紫外最大吸收波长随溶剂极性的增强产生轻微的红移，荧光最大发射波长随溶剂极性的增强产生明显的红移，表明三种叔胺的最低激发单重态具有ππ*跃迁的特性，这对于激态复合物的生成以及其后的光致还原反应和提氢反应的发生都非常有利。
