Show affiliationsWe report the miscibility and molecular orientation of carbazole (CA) molecules in the mixed Langmuir and Langmuir–Blodgett (LB) films of CA in polymethyl methacrylate (PMMA) and stearic acid (SA) matrices. The π-A isotherm confirms the formation of stable Langmuir films of CA mixed with either PMMA or SA at air–water interface. Characteristics of area per molecule versus molefraction and collapse pressure versus molefraction reveal complete demixing of CA and the matrix PMMA/SA molecules in the mixed films. Absorption spectroscopy certainly confirms the fact that CA molecules have preferred orientation on the substrate of the LB films.
