摘　　要：合成了新型质子给体的荧光探针化合物2,3-双(4-二甲胺基苯基)喹喔啉(QBDMA)。利用紫外-可见(UV-Vis)吸收、红外吸收和氢核磁共振等光谱手段对该化合物进行了分子结构表征,同时分析其电化学性质和光致发光性质。研究了该化合物在不同条件下的光致发光光谱。最后在B3LYP1/6-31G*水平上优化其基态结构,并对其UV-Vis吸收光谱进行了理论模拟。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.
