Abstract

Nanostructured organic thin films with polarized luminescence are obtained by means of the slow vapor deposition of fuorescent liquid crystalline dipolar molecules on the surface of the rubbed polyamide layer. Based on the polarized photoluminescence measurements, the polarization degree of thin film based on blue-emitting organic liquid crystalline molecules 4-(n-pentyl)-3-chloro-4′′′-trifluoromethoxy-[1,1′, 4′, 1′′, 4′′, 1′′′-quaterphenyl] (M-BLUE) was found to be 29%, and for red-emitting 4-(dicyanomethylene)-2-(4-amylcyclohexyl)-6[4-(dimethylaminostyryl)]-4H-pyran molecule (M-RED) it is as high as 78%. It can be connected with the higher dipole momentum of M-RED molecule (15) than M-BLUE (3.45), and can be ascribed to its higher interaction with polyamide matrix.
