Abstract
This work reports on the first research of the aligned film based on nematic blend of LC polymer PFO (poly(9,9-di-n-octylfluorenyl-2,7-diyl)) and lanthanidomesogen. Alignment of a blend was carried out by its deposition on a quartz substrate modified with orientant (Nylon 6). The film has polarized luminescence properties with twofold change of intensity due to film alignment.

Keywords: nematic blend, polymer PFO (poly(9,9-di-n-octylfluorenyl-2,7-diyl)), lanthanidomesogen, aligned film, polarized luminescence
