Abstract
In this study isatin and its novel Schiff base as a new red fluorescent material for organic light emitting diodes (OLEDs) are used for red color OLEDs. We fabricated OLEDs with the configuration of indium tin oxide/4.4-Bis(N-carbazolyl-1,1-biphenyl/red emitter/HGH2/Alq3/Li/Al which the electrical and optical properties of devices have been investigated. Their photoluminescence and electroluminescence properties for isatin and its Schiff base were examined and compared. The electroluminescent spectra of these materials ranges from 593 to 645 nm and their bandgaps are between 2.1 and 1.92 eV. The Commission International De L’Eclairage (1931) coordinates of these two compounds were measured and found to be (0.4325, 0.4329) and (0.4077, 0.4128) for two employed chromophores.
