Organic low molar mass fluorescent materials show exceptional potential for use in new-generation light sources, such as organic light-emitting devices (OLEDs). It is anticipated that new materials would enable organic electronic devices to be constructed with higher efficiency and stability, simpler device structures and reduced environmental impact.
In the frame of the SOLID project, development of new donor – acceptor organic heavy metal free fluorescent materials as sensibilizators for delayed fluorescence emitters in active layers of OLEDs, will be performed.
Project funding:
KTU R&D&I Fund
Project results:
Novel organic compounds synthesized during the project are thermally, electrochemically stable and have efficient emission. Such compounds can be used in OLED structures. Some compounds exhibit a pronounced sensitivity of the fluorescence spectrum to environmental polarity. The most efficient material was tested in a TTA emission-based OLED device exhibiting external quantum efficiency of 4.4%, and turn-on voltage of 5V.
Period of project implementation: 2019-04-01 - 2019-12-31
