We have previously demonstrated the formation of well-organized ultra-thin films of lead halide-based 2D layered organic-inorganic hybrid perovskites (2D LHPs) by immersing Langmuir-Blodgett (LB) films of octadecylamine (ODA) in aqueous solutions containing lead halides. However, the mechanism underlying the intercalation process, which involves a significant volume change, remains poorly understood. In this study, we present our recent findings on the characterization of film thickness using white light interferometry and the in-situ observation of the intercalation process through bright-field microscopy.
