Blue emitting amino-DPQ with PS and PMMA phosphors for organic light emitting diode

New conjugated polymer, 2(4′-aminophenyl)-4-phenylquinoline i.e., amino-DPQ have been synthesized by Friedlander condensation method at 140 °C. The Optical, structural and thermal properties of the amino-DPQ has been studied. The blended thin films of amino-DPQ with PMMA and PS at different wt% concentrations have been prepared. The UV–vis absorption spectra could provide a good deal of information on the electronic structures of the polymeric compound. When powder form of amino-DPQ is excited at 385 nm, it emits intense blue light of wavelength 486 nm. The blended thin films of amino-DPQ with PMMA and PS at different wt% concentrations show the emission peak in the range of 415–450 nm. Hence, the blue emitting 2(4′-aminophenyl)-4-phenylquinoline (amino-DPQ) has generated considerable interest owing to their good photoluminescence efficiencies.
