((tetraphenylporphyrinyl)methyl)triphenylphosphonium氯化物与苯甲醛(CHO−C6H4−R；R=H，NO2，NMe2，OME，Me，CHO)反应生成苯乙烯基卟啉衍生物。用电化学、电子吸收光谱和共振拉曼光谱电化学技术研究了这些新的苯丙基取代的卟啉。苯乙烯基上的取代基对卟啉核心的电子光谱有一定的扰动作用。共振拉曼数据表明，在4-NO2化合物中，观察到了卟啉核心与NO2基团之间的电荷转移相互作用。
The reaction of ((tetraphenylporphyrinyl)methyl)triphenylphosphonium chloride and benzaldehydes (CHO−C6H4−R; R = H, NO2, NMe2, OMe, Me, CHO) yields the styryl porphyrin derivatives. These new styryl-substituted porphyrins have been studied using electrochemistry, electronic absorbance, and resonance Raman spectroelectrochemical techniques. The substituents on the styryl group have a modest perturbation on the electronic spectrum of the porphyrin core. The resonance Raman data suggest that a charge-transfer interaction is observed between the porphyrin core and the NO2 group for the 4-NO2 compound.
