摘要

In this study isatin and its novel Schiff base as a new red flu-orescent 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/HGH_2/Alq3/Li/Al which the electrical and optical properties of devices have been inves-tigated. Their photoluminescence and electroluminescence properties for isatin and its Schiff base were examined and compared. The electrolu-minescent spectra of these materials ranges from 593 to 645 nm and their bandgaps are between 2.1 and 1.92 eV. The Commission Interna-tional 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.
