研究了C_(60)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/C_(60)(1:1)的混合单层膜中,C_(60)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/C_(60)(1:1)的混合单层膜中,C_(60)则以聚集体的形式均匀分散到TAPP的聚集体中。尽管均有C_(60)聚集体形成,但由于卟啉衍生物结构的差异,C_(60)在两种混合膜中的分散状态大不相同。
The effects of C_ (60) on the degradation of tetraphenylporphyrin derivatives 5,10,15,20-tetra (p-capric acid) phenylporphyrin (TDPP) and 5,10,15,20- (Acetic acid a oxy) phenyl porphyrin (TAPP) monolayer membrane dispersion state. The low-angle X-ray diffraction experiment of the mixed multilayers formed by mixed membrane and arachidic acid (AA) and the UV-Vis spectra of mixed single-layer LB membrane showed that the π-A isotherm of mixed monolayers at air / Cd2 + In the mixed monolayers of TDPP / C_ (60) (1: 1), C_ (60) was embedded in the cavity formed by the aliphatic chains of TDPP molecules in the form of single molecule or Victoria Lord. Guest system. In mixed monolayers of TAPP / C_ (60) (1: 1), C_ (60) was uniformly dispersed as aggregates into the aggregates of TAPP. Despite the formation of C_ (60) aggregates, the dispersion state of C_ (60) in the two kinds of hybrid membranes varies greatly due to the difference in the structure of porphyrin derivatives.
