LB薄膜上芪盐的结构分析

STRUCTURE ANALYSIS OF STILBAZIUM SALT IN LB FILM

对在不同表压下芪盐多层ＬＢ膜及芪盐与二十酸混合材料多层ＬＢ膜透射光谱的研究表明，ＬＢ膜上芪盐处于固相态，且随着表压增加可从一种固相态向另一种固相态转变．两种固相态分别对应两种芪盐Ｈ聚集体．在混合材料的ＬＢ膜中不仅存在芪盐的两种聚集体，还存在芪盐与二十酸的分子相互作用，它引起芪盐聚集体数的减小。

We measured the transmission spectrum of stilbazium salt LB film and LB film of mixed stilbazium salt and tweaty acid.According to the experiments, we got the following results.Stilbazium salt in LB film was in the form of the solid state.It changed from a kind of the solid state to another with the increment of the surface pressure.Two kinds of the solid state corresponded respectively to two kinds of the aggregation H of stilbazium salt. In LB film of mixed material,not only there were two kinds of the its aggregation,but also there was the molecule interaction between stilbazium salt and twenty acid. This interaction could reduce the quantity of the aggregation.
