Abstract

Langmuir (L) and Langmuir-Blodgett (LB) films of perylene-like dye and its binary mixtures with 4-octyl-4'-cyanobiphenyl (8CB) and 4-pentyl-4"-cyano-p-terphenyl (5CT) have been investigated. On the basis of the surface pressure-mean molecular area isotherms, the molecular organization on the air-water interface has been determined. The spectroscopic study of the LB films has allowed conclusions to be drawn about the alignment of the molecules on the quartz slides. The absorption and fluorescence spectra of the LB films of the perylene-like dye have revealed the formation of self-aggregates.
