Synthesis and Analysis of Novel Quinoxaline Derivative

4,4′-(quinoxaline-2,3-diyl)bis(N,N-dimethylaniline)(QBDMA) was synthesized and its structure was fully characterized by UV-Vis absorption spectra,IR spectra and 1H NMR spectra.The electrochemical analysis was also performed to determine the energy of the frontier molecular orbitals of QBDMA.It was found that QBDMA can be used as the pH sensor of the proton donor compounds based on the analysis of its photophysical properties.At last,the ground state geometry structure of QBDMA was optimized,and the UV-Vis absorption spectra of QBDMA were simulated in DMF and EtOH media at B3LYP1/6-31G* level.
