OLED display application of 2-(6-Fluoro-2-oxo-2H-chromen-4-ylmethoxy)-benzoic acid methyl ester derivative

Abstract

White light emitting diodes (WLED) has received much importance due to their vast applications in various sensors, lightning devices and display etc. By mixing certain amount of green, red and blue, white light can have produced. Therefore, we made an attempt to produce a LED application device making use of organic compounds. Hence, we synthesized 2-(6-Fluoro-2-oxo-2H-chromen-4-ylmethoxy)-benzoic acid methyl ester (2-FBME) coumarin. In this present work the band gap energy is calculated and the photoluminescence spectra of 2-FBME molecule is studied in different solvents, this result shows the compound can be used to produce the desired wavelength. Hence,2-FBME possesses high color purity, good CIE chromaticity coordinate, and they would have potential organic light emitting devices (OLED) application, this simple method is used to produce the blue light as blue component can play important role in WLED.
