摘　　要：利用紫外-可见吸收光谱研究了两种具两条十六烷氧基链的两亲卟啉（cis-P2和trans-P2）的单分子膜的Cu2＋嵌入作用.两种卟啉单分子膜在膜／液界面均能嵌入Cu2＋，嵌入速率取决于膜中卟啉分子的排列和聚集态，Cu2＋较易嵌入形成J-聚体的trans-P2，而嵌入形成氢键聚集体的cis-P2较慢.Cu(Ⅱ) ion incorporation into the monolayer and LB films of two kinds of amphiphilic porphyrins with double hexadecyloxyl chains (cis-P2 and trans -P2) was investigated by using UV-vis absorption spectroscopy. The incorporation rate is dependent upon the arrangement and the aggregation behaviours of porphyrins. It is easier to incorporate Cu(Ⅱ) into J - aggregate of trans-P2 than into hydrogen - bonded aggregate of cis - P2.
