Investigation on Photoluminescence Behaviour of 2, 3-Diphenylquinoxalin-6-Vinyl Benzaldehyde

Authors: R Padma, M Sathiya, S Guhanathan

Poly (p-phenylene vinylene) is one of the most important classes of conjugated polymers, with a wide range of applications, such as lightemitting diodes, optoelectronic devices etc. Electroluminescence from OLEDs arises from the radioactive decay of excitation generated by the recombination of electrons and holes injection from two opposite electrodes into the emissive polymer layer. Quinoxaline is a useful n-type building block with high electron affinity and good thermal stability. It has been successfully incorporating small molecules to find utility as electron transport materials in multilayer OLEDs based on PPV. Hence, vinyl benzaldehyde containing quinoxaline derivatives was synthesized using 6-methyl-2, 3-diphenylquinoxaline with terephthaldicarboxaldehyde via Wittig reaction. The structures of synthesised compounds were confirmed by FT-IR, 1 H, 13C, 31P-NMR, and MASS spectral data. The result of photoluminescence studies showed that vinyl benzaldehyde capped quinoxaline exhibited green emission maxima at shorter wavelengths of 454nm.
