摘要
采用微波加热合成法,以对氰基苯甲醛、苯甲醛和吡咯为原料,丙酸为溶剂和催化剂合成了一系列含氰基的卟啉化合物,产物通过IR、UV-Vis、1HMNR进行了表征,讨论了化合物结构对光谱性质的影响。UV-Vis吸收光谱显示:随着分子中氰基数目增加,卟啉分子吸收红移;采用微波辐射加热,反应时间10 min,两种芳醛和吡咯的投料比为2∶2∶4,得到含1～2个氰基的卟啉化合物总收率可达17%。
Series of cyano - porphyrins was synthesized under microwave irradiation with cyano - benzaldehyde, ben- zaldehyde and pyrrole as raw material and propionic acid as solvent and catalyst. The structures of the target products were- characterized by IR, UV - Vis, and 1HNMR spectrum. The influence of structure to the spectral property was discussed. The results showed the UV - Vis absorption band red 2 shifts as cyano group number increased in molecules, reaction time was 10 min on microwave radiation, feed ratio of two kinds of aromatic aldehydes and pyrrole was 2 ： 2 ： 4, and the total yield of the porphyrin compounds of containing 1 -2 cyano reached 17%.
