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.
