    Organic molecules adsorbed on an inorganic nanosheet often form a nanometer-sized cluster. In this study, we propose novel strategy for controlling the cluster size. We fabricated hybrid Langmuir-Blodgett (LB) films consisting of N-n-octadecyl-4-[2-(4-dimethylaminophenyl)ethenyl]pyridinium bromide and a clay mineral, sodium montmorillonite, with varying subphase temperature. As a result, the size of the clusters was found to be decreased from 300 nm to 50 nm by increasing the subphase temperature from 10 degrees C to 40 degrees C.
