本文介绍了卟啉-蒽醌-苦味酸(P-AQ-T)三联体化合物的合成。以卤乙酰卤与1,5-二氨基蒽醌反应, 生成1,5-二(卤乙酰氨基)蒽醌, 再与卟啉和苦味酸联结, 得到P-AQ-T三联体。同时进行了荧光性质的比较。

This paper reports the synthesis of a porphyrin-anthraguinone-trinitrophenol triplex compound (P-AQ-T). linking 5-p-hydroxyphenyl-10, 15, 20-triphenylporphyrin and picric acid by 1,5-di(haloacetamido) anthraguinone forms P-AQ-T. comparing UV and fluorescence spectroscopy of P-AQ-T, P-AQ and TPP shows that their fluorescence guantum yields are TPP>P-AQ>P-AQ-T. this result suggests that in this triplex there exists more stsable charge separated state P+-AQ+-T=P+-AQ-T+ because of the trinitrophenol oiety as electron acceptor.
