以对甲基苯甲酸(p-methylbenzoic acid,简写为PMBA)为骨架,通过霍纳尔-沃兹沃思-埃蒙斯(HWE)反应合成了7个电子给体-π-电子受体(D-π-A)型有机双光子吸收(TPA)材料分子,化合物结构用核磁共振氢谱(1 H NMR)和质谱(MS-EI)进行了表征和分析;光学性质用紫外-可见(UV-Vis)光谱、荧光(PL)光谱进行了研究,结果发现,在5.0×10-6 mmol/L二氯甲烷溶剂中,各化合物的紫外最大吸收波长在368～396nm之间,而最大发射峰荧光发射波长位于489～525nm之间,发出较强的蓝光。是一类具有潜在应用的新型有机发光材料分子。
Seven p-methylbenzoic acid (PMBA) skeletons were synthesized by Horner-Wadsworth-Emmons reaction (HWE) D-π-A) type organic two-photon absorption (TPA) materials were synthesized and characterized by 1H NMR and MS-EI. The optical properties were characterized by UV-Vis -Vis) spectroscopy and fluorescence (PL) spectroscopy. The results showed that the maximum ultraviolet absorption wavelength of each compound was between 368 and 396 nm in 5.0 × 10 -6 mmol / L dichloromethane solvent, and the maximum emission peak Fluorescence emission wavelength is located between 489 ~ 525nm, emitting a strong blue light. Is a class of potential applications of new organic light-emitting material molecules.
