  The lowest excited states of copper porphyrins

  摘要：

  Relaxation processes of excited copper porphyrins were studied with relevance to the structure of the substates of the lowest excited states. Lifetimes of luminescence at room temperature were determined as 17, 29, 69, and 105 ns for T(EtO)PPCu [T(EtO) PP: 5, 10, 15, 20-tetra (p-ethoxyphenyl)porphin], TPPCu(TPP: 5, 10, 15, 20-tetraphenylporphin), TFPPCu[TFPP: 5, 10, 15, 20-tetra(pentafluorophenyl)porphin], and OEPCu(OEP: 2, 3, 7, 8, 12, 13, 17, 18-octaethylporphin) in toluene, respectively. Emission intensities and lifetimes of OEPCu and TFPPCu measured as a function of temperature show a variation ascribed to a Boltzmann distribution between the lowest trip–doublet and –quartet with an energy gap of 300–400 cm−1. The anomalous temperature dependence for TPPCu and T(EtO)PPCu is explained by a larger energy gap and larger vibronic distortions in the excited state. The difference in behavior is attributed to the orbital nature of the triplet: ‖2,4[b31(a1e)]〉 for OEPCu and TFPPCu but ‖2,4[b31(a2e)]〉 for TPPCu and T(EtO)PPCu. The assumption of a low energy charge transfer state is not necessary for our analysis.

  study reports the synthesis of two novel zinc porphyrin families bearing four or eight alkoxy chains at their peripheral phenyl rings, with the length of the alkoxy chains ranging from 2, to 6, and to 12 carbon atoms. All zinc porphyrin derivatives were fully characterized with respect to their photophysical and electrochemical features. The zinc porphyrins could be processed into thin films which, depending

  这项研究报告了两个新颖的锌卟啉家族的合成，这些家族在其外围苯环上带有四个或八个烷氧基链，烷氧基链的长度范围为2至6和12个碳原子。所有锌卟啉衍生物均已就其光物理和电化学特性进行了充分表征。卟啉锌可以加工成薄膜，这取决于芳基取代基上的烷氧基链的长度，被发现是有序或无序的，正如通过光谱和显微技术所揭示的那样。与无序膜相比，包含有序自组装的膜显示出显着增强的电导率。这导致了在较低偏压下发生的电致发光响应的显着差异。此外，
