Paper Title
BLUE LIGHT EMITTING ORGANIC LUMINESCENT MATERIAL, NITRO-DPQ

Abstract
The synthesis of Nitro substituted 2, 4-diphenyl quinoline has been synthesized by Friedlander Condensation at 140 °C. The photophysical properties of derivative of quinoline have been studied in acidic as well as basic solution. The results show that derivatives of quinoline are a promising class of materials for use in optical and optoelectronic applications. Powder form of nitro-diphenyl quinoline exhibits photoluminescence with emission maximum at 468 nm when excited at 383 nm. The PL spectra of blended films showed strong band in the blue region at 425 - 430 nm, when excited at 383 nm. In this study we focus our attention basically on the comparative study of optical properties of our sample in solvent. Index Terms—Photoluminescence, Diphenyl quinoline, Friedlander condensation.
