A novel technique to improve the orientational order of chromophores in Langmuir-Blodgett (LB) films utilizing molecular mixing of two homologous amphiphile was proposed. Two azobenzene-linked amphiphiles which possess the same chemical structure except for a hydrophilic head group formed a molecularly mixed monolayer at the air-water interface. The polar amphiphile with a nitro group as the head group oriented vertically through the molecular mixing with the nonpolar amphiphile. The orientation was preserved in an LB film consisting of the mixed monolayer.
