Abstract: 

For the application in organic light-emitting diodes, the efficient new derivative of 2, 4-diphenyl quinoline i.e., 2(2’,4’-dichloro phenyl)-4-phenyl quinoline (dichloro-DPQ) has been synthesized by Friedlander condensation at 140 °C. Blended films of dichloro-DPQ with poly (methyl methacrylate) (PMMA) and polystyrene (PS) at different weight % concentrations like 10, 5 and 1 wt% have been prepared. Structural and optical characterization techniques were used to characterize the crystalline powder. The photoluminescence in synthesized dichloro-DPQ polymeric compound shows emission peak in blue region at 462 nm in powder form and PL emission in dichloro-DPQ with PMMA and PS with different wt%; we get hypsochromic shift. Optical properties of dichloro-DPQ make it possible candidate material as blue organic phosphor for the field of light industry. Copyright © 2012 VBRI Press.
