Objective: design, synthesis and study of new electroactive emitting materials that would produce efficient organic light-emitting diodes (OSVD). Methods: spectrophotometry, photoluminescence spectra, electroluminescence. Main results: New white light emitting materials (composites based on organic dyes AI15, dg75s, dg78s in a polymer matrix) have been designed and synthesized. The optical and photophysical properties of the materials crested during the Project have been investigated. The spectral position of the luminescence bands for dyes AI15, dg75s, dg78s (375-550 nm for AI15, 400-600 nm for dg75s, dg78s) suggests these dyes potentially promising candidates for use as fluorescent emitters for "white" hybrid composites based on carbazole-intensive polymer matrices and phosphorescent dye v545 (emits at 520-675 nm). There is a clear picture of the energy transfer between the matrix and PEPC each of the studied dyes in the corresponding composite films (mass fraction of the dye was 1%). This fact suggests these dyes potentially promising for the creation of such composites with effective transfer of excitation energy from the matrix to the emitting centers - dyes.
