This project is focused on synthesis and characterizations of the versatile exciplex-forming donor-acceptor (D-A) compounds and the development of white organic light-emiting diodes (OLEDs) based on such compounds with a view to make the solid-state lighting maximally effective. We propose the development of new type exciplex forming foundation, enabled the formation two different types of D-A/D and D-A/A exciplexes in the same time. The utilization of the latter would allow to obtain white emission in simplified OLED structure.
Projects funded by the Research Council of Lithuania (RCL), Projects carried out by researchers’ teams
A prototype of white low-cost organic light emitting diodes will be developed with simplified structure due to the employment of the newly synthesized versatile exciplex-forming D-A compounds as emitters exhibiting thermally activated delayed fluorescence (TADF); high photoluminescence quantum yields (PLQY); high and balanced charge mobilities (~10-3 cm2/Vs); high triplet-energy values (>2.8 eV) and appropriate energy levels.
