Highly ordered smectic liquid crystal phases that emerge through the mixing of different liquid crystal materials, exhibiting a higher degree of order than the liquid crystal phases of the individual components, are referred to as induced smectic phases. Owing to their two-dimensional layered structure, smectic liquid crystals are advantageous for the formation of uniform thin films. However, only a few studies have reported the fabrication of thin films of induced smectic phases on substrates. In this study, thin films of a 4-cyano-4′-pentylbiphenyl (5CB) and N-(4-ethoxybenzylidene)-4-butylaniline (EBBA) binary mixture were prepared from toluene solutions, and their structures and temporal evolution were investigated.
