摘要

制备了单层和多层BDN(双(4-二乙烷二硫苯)镍)-SA(硬脂醇)LB (Langmuir-Blodgett)薄膜，并用紫外-可见光谱研究了其微晶结构域的特性。-近红外光谱和原子力显微镜。结果表明，BDN-SA LB膜由许多球状微晶畴组成，尺寸从几十到几百nm不等。多层LB膜的原子力显微镜图像显示，结构域表面存在有序的分子排列，类似于马赛克结构。并给出了BDN-SA LB膜的畴的平均尺寸与膜的厚度之间的关系。

Microcrystalline domains of monolayer and multilayer BDN-SA Langmuir–Blodgett films

Monolayer and multilayer BDN(Bis(4-diethyannodithiobenzil)nickel)-SA(stearyl alcohol) LB (Langmuir–Blodgett) films were prepared and the characteristics of microcrystalline domains were studied using UV–vis.–NIR and AFM. The results indicate that BDN-SA LB films consist of numerous ball-like microcrystalline domains at size scales from a few tens to a few hundreds of nm. AFM images of a multilayer LB film show that well-ordered molecular arrangements exist on the surface of domains which resemble a mosaic structure. The relationship between the mean size of the domain of a BDN-SA LB film with the thickness of the film was also shown.
