Synthesis and characterization of β-substituted 5,10,15,20-tetraphenyl-21,23-dithiaporphyrins are reported. The absorption and emission spectra exhibited large bathochromic shifts due to nonplanarity of porphyrin ring which is induced on β-substitution.
报告了 β 取代的 5,10,15,20-四苯基-21,23-二
硫代
卟啉的合成和表征。由于
卟啉环的非平面性,其吸收光谱和发射光谱表现出很大的浴色偏移,而这种非平面性是由β取代引起的。
