四苯基卟啉氧合配合物的室温固相合成、表征及氧合性能

Solid State Synthesis,Characterization and Properties of Oxygenated Tetraphenylporphyrin

采用固相反应合成了四苯基卟啉与Fe2+、Co2+的配合物。在室温下,将其与分子O2作用,提纯后得到两种固态氧合配合物。通过元素分析、红外光谱、核磁共振氢谱、电导、热分析(TG/DTA)、紫外光谱等测试手段确定了氧合配合物的组成为[Co.TPP.O2](NO3)2.2H2O、[Fe.TPP.O2]Cl2.2H2O,可知1mol配合物吸收了1molO2。采用失重法测定了氧合配合物中的配位氧,确定1mol金属配合物吸收1molO2形成超氧配合物。

Fe^2＋ and Co^2＋ porphyrin complexes were synthesized by solid state reaction at room temperature. The oxygen adducts [ Co·TPP· O2 ] （ NO3 ）2·2H2O, [ Fe·TPP· 02 ] Cl2·2H2O were obtained and characterized by elemental analysis, IR spectra, ^1H NMR, TG/DTA, UV-vis and molar conductance. The contents of coordinated oxygen in the oxygenated complexes were also determined by weight method. It was found that one mole of oxygen coordinated to one mole of metallporphyrin and the superoxo type oxygenated complexes were formed.
