9-烷基亚胺-4,5-二氮杂芴LB膜内分子取向的研究

Study on The Orientation of AIDF in LB Films

用自制的两亲分子9-烷基亚胺4,5-二氮杂芴制备了多层LB膜,用偏振FT-IR透射光谱测定了化合物中长脂肪链在LB膜内的取向,并运用偏振UV-vis光谱测定了LB膜内二氮杂芴环的取向,结果表明长指肪链的轴线与膜表面法线间的夹角约为50°,芴环的长轴与膜表面法线间的夹角约为66°,由此提出了LB膜内分子排列的结构模型。

:In this paper the multiplayer LB films of AIDF are prepared. Polarized FT-IR spectrum and polar-ized UV-Vis spectrum are respectively used to calculate the orientation of alkyl chains component and the ori-entation of rings of AIDF in LB films. The results show: the angle between the alkyl chain axis and the vertical line of the film surface is 50? the angle between the ring axis and the vertical line of the film surface is a-bout66? Therefore we assum the structural model of molecules which arrang in LB films.
