摘要
运用紫外可见（ＵＶｖｉｓ）吸收光谱研究了５，１０，１５，２０四（４十六烷氧基苯基）卟啉（ＴＨＰＰ４）在四氢呋喃水中的聚集态及混合溶剂配比、温度等对聚集的影响．当水中四氢呋喃（ＴＨＦ）含量适当时ＴＨＰＰ４可形成Ｂ带劈裂聚集体，这种产生强激子作用的聚集是由溶剂极性所引起．利用变温技术可以获得ＴＨＦ水的最佳配比，即水中ＴＨＦ的体积分数为０．１时ＴＨＰＰ４聚集最完全，分子激子作用最强．
The aggregation of 5,10,15,20tetrakis(4hexadecyloxyphenyl)porphyrin(THPP 4)in the mixed solvent of THF and water have been investigated by using UVvis absorption spectroscopy.The effect of mixed proportion and temperature upon the aggregation was discussed.The spectral properties show that THPP 4 may form Bstate splitting aggregate as the percent of THF is reasonable,the aggregation depends upon the polarity of the solvent mixture.Temperature studies were made and the results show that the most reasonable volume fraction of THF in the solvent mixture for THPP 4 to aggregate well.
