摘要： 研究了C60在四苯基卟啉衍生物5,10,15,20-四-对(癸酸a氧基)苯基卟啉(TDPP)及5,10,15,20-四-对(乙酸a氧基)苯基卟啉(TAPP)单层膜中的分散状态。空气/Cd2+水溶液界面上混合单层膜的π-A等温线、混合膜与花生酸(AA)形成的交替多层膜的低角X射线衍射实验及混合单层LB膜的UV-Vis光谱表明,在TDPP/C60(1:1)的混合单层膜中,C60以单分子或(和)聚集体的形式嵌入TDPP分子的脂链所形成的空腔中形成了二维主。客体系;在TAPP/C60(1:1)的混合单层膜中,C60则以聚集体的形式均匀分散到TAPP的聚集体中。尽管均有C60聚集体形成,但由于卟啉衍生物结构的差异,C60在两种混合膜中的分散状态大不相同。

Abstract: The dispersing states of C60 molecules in mixed monolayers of TDPP/C60(1:1) and TAPP/C60(1:1)have been studied in this paper,Here,TDPPdenotes 5,10,15,20-tetra-4-oxy(decanoic acid)phenylporphyrin, and TAPPdenotes 5,10,15,20-tetra-4-oxy(acetic acid)phenylporphyrin,The π-A isotherms of mixed monolayers on air/Cd2+ aqueous solutioninterface, the low angle X-ray diffraction results of the alternate multilayers of TDPPor TDPP/C60 with arachidic acid and the UV-Vis spectra of mixed LBmonolayers show that,in the mixed TDPP/C60 monolayer C60 aggregates or(and) single C60.molecules are incorporated into the cavities of TDPPmolecules containing long alkyl chains,.but in the mixed TAPP/C60 monolayer, C60 aggregates distribute among the TAPPaggregates.
