Abstract
Aligned organic thin films with polarized luminescence are obtained by means of the slow vapor deposition of fluorescent blue emitting organic liquid crystalline dipolar molecules, 4-(n-penthyl)-3-chloro-4‴-trifluoromethoxy-[1,1ʹ,4ʹ,1ʺ,4ʺ,1‴-quaterphenyl] (M-BLUE), and red emitting molecules, 4-(dicyanomethylene)-2-(4-amylcyclohexyl)-6[4-(dimethylaminostyryl)]-4H-pyran molecule (M-RED), on the surface of the rubbed conducting polymer (PEDOT:PSS). The polarization degree of M-BLUE thin film was found to be 31%, and for M-RED it is 48%. Essential luminescence quenching by PEDOT:PSS was observed. Strong blue shift of M-RED luminescence on PEDOT:PSS substrate is caused probably because of strong interaction between these counterparts.
