Zusammenfassung: | FIELD: polymer materials. ^ SUBSTANCE: invention provides luminescent material showing semiconductor properties and being product of complex polymerization in glow discharge, which is formed as a supported polymer layer located either between electrodes or on any of electrodes. Starting pyrromethene complex is difluoroborate complex of 1,3,5,7,8-pentamethyl-2,6-diethylpyrromethene (Pyrromethene 567). Method of preparing luminescent semiconductor polymer material comprises glow-discharge polymerization for 2 to 120 min of Pyrromethene 567 vapors at temperature preferably 250-350°C, pressure 10-1 to 10-2 Pa, and discharge power 0.5-3 W. Resulting luminescent polymer is characterized by thickness preferably 0.001-10 mum, conductivity 1.10-10 to 5.10-10 Ohm-1cm-1 (20°C), luminescence emission maximum in the region of 540-585 nm at band halfwidth 55-75 nm. Polymer is obtained with quantum yield 0.6-0.8 and is designed for creation of film light-emitting devices. ^ EFFECT: improved performance characteristics of material. ^ 13 cl, 3 ex |
