Joint research by Pavel Arenyan group (IOS) and scientists from the Kaunas University of Technology on new OLEDs has been published in the Journal of Materials Chemistry C (IF=7.059).
A procedure for post-functionalization by 3,6-di-tert-butyl-carbazole or 3,7-dibromophenothiazine of dicyanopyridines has been reported. Pyridine ring in these structures exists in a twist-conformation in solid-state. Green and orange OLEDs with 3,6-di-tert-butyl-carbazole-containing emitter exhibiting normal TDAF, showed a high maximum EQE of 25%.
