摘要
四(4氨基苯基)卟啉(TAPP)是含有4个反应活性基团的卟啉衍生物,可在模拟某些生物过程或氧化还原反应的树枝状或簇状分子中作为富电子中心,也可直接用来制备光电器件或作为光电功能聚合物的功能单体和交联剂,因此,TAPP的合成研究具有重要意义[1]....
An improved method for synthesis of tetra(4 nitrophenyl)porphyrin(TNPP) and tetra(4 aminophenyl)porphyrin(TAPP) is reported. 4 Nitrobenzaldehyde was cyclized with pyrrole in refluxing nitrobenzene using a lactic acid catalyst and then precipited by methanol giving TNPP of 22 3% yield in high purity. Reduction of TNPP with SnCl 2·2H 2O in concentrated HCl gave high purity TAPP in yield of 81 5%.
