Abstract
A novel 2,2’-Bis(4-Phenylquinoline )1,4 phenylene(BPQ-P) organic phosphor was synthesized in Aragon(Ar) and Nitrogen (N2) atmosphere at 140oC by using Friedlander Condensation reaction. Based on our previously synthesized DPQ, we systemically designed some novel derivatives with tuned optical properties & the compound showed blue emission under a UV source. The synthesized organic phosphor is assessed by various characterization techniques such as FTIR and NMR spectroscopy. Using excitation and emission spectra were analysed the properties of PL in organic compounds. The synthesized organic phosphors show bright emission in the blue region, with the peaks at 483nm for 4-phenylquinoline. The physical and photoluminescence properties of these organic compounds reveal promising blue emitters for high efficiency organic light emitting diodes (OLEDS) and it may also find device applications as n-type semiconductors.
