  摘要：

  Chloroiron（III）四苯基卟啉，CIFE III TPP，在脱气乙醇光还原到屈服铁（II）四苯基卟啉，铁II在用UV光照射TPP。在355周nm激光光解的研究已经证实，对于Fe的形成的初始产量II TPP得到显着的增加CIFE的浓度降低III TPP：φ = 0.015 5.35×10 -6摩尔分米-3 CIFE III TPP和φ = 0.01在1.0×10 -4摩尔分米-3 CIFE IIITPP。在低浓度的CIFe III TPP下，通过光反应性铁（III）卟啉的形成来解释浓度对量子产率的影响。

  Photochemical reactions of carbonyliron(II) tetraphenylporphyrins, (CO)(L)FeIITPP (L = ethanol and imidazole) and bisimidazoleiron(II) tetraphenylporphyrin, (Im)2FeIITPP, in ethanol were systematically investigated by laser flash photolysis. The yields for photodissociation of CO from (CO)(C2H5OH)FeIITPP and (CO)(Im)FeIITPP were determined to be 0.53 and 0.9 at room temperature, respectively. On the basis of the quantum yield measurements in the temperature range 180-300 K, the activation energies for decarbonylation obtained for (CO)(C2H5OH)FeIITPP and (CO)(Im)FeIITPP were 0 and 4.9 kcal mol-1, respectively. No dissociation of the ligand L from (CO)(L)FeIITPP was detected. The photochemical dissociation of the axial imidazole from (IM)2FeIITPP was also studied. The yield for photodissociation of imidazole obtained was 0. 1 8 at room temperature, and the activation energy was evaluated to be 2.6 kcal mol-1. It was found that (Im)(C2H5OH)FeIITPP produced by photolysis of both (CO)(Im)FeIITPP and (IM)2FeIITPP undergoes spontaneous base elimination to give (C2H5OH)2FeIITPP and imidazole, Im. The reactive excited states responsible for photodissociation of the axial ligands as well as the spontaneous base elimination reaction are discussed in detail.
