Langmuir-Blodgett膜技术是一种受到人们广泛重视的分子有序化和定向化方法.利用该技术可在液面获得二维紧密排列的单分子层,并可将其转移至固体表面实现多层组装以构成各类分子器件.液界面上单分子层的结晶过程和相行为,包括相分离、相转变等已被Mohawld等人用荧光显微镜和Mobius等人用Brewster角显微镜观察过.然而,对它们转移至固体表面上状况的研究却几乎未见报道.特别是用这两种分析手段根本无法观察到单分子层中 Langmuir-Blodgett membrane technology is a kind of molecular ordering and orientation method widely used by people.With this technology, two-dimensional closely arranged monolayers can be obtained at the liquid surface and transferred to the solid surface to realize multi-layer Assembled to form various molecular devices.The crystallization process and phase behavior of the monolayer at the liquid interface, including phase separation, phase inversion, etc., have been observed with a Brewster angle microscope by Mohawld et al. And Mobius et al. However, However, few reports have been reported on the status of their migration to solid surfaces, especially in both monomolecular layers
