摘要
用混合醛与吡咯缩合,合成了七种对称及不对称的中位硝基取代苯基卟啉及其还原产品:TPP(NO_2)_n,TPP(NH_2)_n[n=0,1,3,4)。研究了它们的吸收光谱,发现苯基上取代基对吸收光谱有较大的影响,而且所用溶剂的极性也会影响光谱的特性;此外,还对这些化合物的荧光光谱进行了测定并讨论。
Seven symmetric or unsymmetric substituted tetraphenylporphyrins TPP(NO_2)_n, TPP(NH_2)_n[n=0, 1, 3, 4]were prepared by condensation of mixed aldehydes with pyrrole. Their absorption spectra were studied. It was found, the spectra are evidently influenced by the substituents on phenyl groups, furthermore, solvents used could affect the characteristics of their absorption spectra. Fluorescence spectra of those compounds were also measured and discussed.
