Optical and photonic properties dependence on HNMB solvents: An emitter molecule for OLEDs

Abstract

The development of organic light-emitting diodes (OLEDs) is very important due to their use in new generation lighting and displays, their color resolution and their unique optical properties. Herein, the change of the electronic and optical properties of a new molecule, 4-[(E)-[(2-hydroxy-1-naphthalenyl)methylene]amino]-3-methyl benzoic acid (HNMB) in different solvents are reported by experimental and advanced theoretical calculations. Optical properties are investigated by calculating the optical absorption wavelength, optical refractive index, optical band gap, optical conductance, angle of incidence, angle of refraction, contrast for different solvents. Finally, due to well-suited photonic and optoelectronic properties, the HNMB can be used as a phosphorescent and OLED material.
