Maleimide based highly luminescent material Cbz-MI with donor acceptor donor (D-A-D) backbone has been synthesized and characterized. An organic light emitting diode fabricated using this material
as emitting layer exhibited EQE of 2.5% in the yellow region of visible spectrum. Due to the small energy gap of materials emitting in this region of spectrum, EQE of OLED is usually limited by various non-radiative decays and high EQE of OLED using this material proves that most of the nonradiative
decay pathways have been avoided by the careful design of molecule and device structure.
Although Cbz-MI did not show TADF properties, but if tailored with right electron donor along with maleimide as an acceptor, such derivatives may exhibit TADF properties
