新型卟啉化合物的合成、结构表征及光谱性质

Synthesis,structural characterization and spectrum property of a series of new β-Octamethyl Tetraarylporphyrins

报道了几种新型卟啉化合物-2，3，7，8，12，13，17，18-八甲基-5，10，15，20-四芳基卟啉的合成及光谱特征．该类卟啉化合物是以芳香醛和二（3，4-二甲基吡咯）-苯基甲烷在醋酸中回流缩合得到，并通过UV—Vis、IR和^1HNMR进行了结构表征．研究结果表明此类卟啉化合物的紫外可见光谱吸收峰和荧光发射峰与β-未取代的四苯基卟啉（TPPH2）相比较有很大红移，其荧光最大发射位置为737nm．

A series of new β - Octamethyltetraarylporphyrins were synthesized by direct condensation of substituted benzaldehyde and his（3,4 -dimethylpyrrole） - arylmethane in refluxing acetic acid. Their structures were characterized by UV -Vis,IR and ^1H NMR. Comparing with tetraphenylporphine（TPPH2 ）, the UV - Vis Soret absorption and fluorescence emission peaks of these the as-prepared compounds have large red - shifts. The maximum peak of fluorescence emission is 737 nm.
