采用两步法合成了5,15-二-(五氟苯基)-10,20-二(2-吡啶基)自由卟啉分子,探讨了反应过程中催化剂用量、反应温度及反应时间对目标产物产率的影响。结果表明,制备中间产物双吡咯基五氟苯基甲烷时,催化剂BF3·Et2O与五氟苯甲醛的物质的量之比为1∶15,制备目标产物的反应温度为145℃,反应时间为1 h,在该条件下目标产物的产率最高达到33.6%。通过MS,IR,UV-Vis,1HNMR,19FNMR及EA测试技术对产物进行了表征,在470 nm的光激发下,该化合物最强发射峰位于711 nm,可以作为潜在的发光材料。
The 5,15-bis (pentafluorophenyl) -10,20-bis (2-pyridyl) porphyrin molecule was synthesized by a two-step method. The effects of catalyst amount, reaction temperature and reaction time on the target Effect of product yield. The results showed that the ratio of BF3 · Et2O to pentafluorobenzaldehyde was 1:15, the reaction temperature was 145 ℃, and the reaction time was 1 at the time of preparing the intermediate of bipyrrolyl pentafluorophenyl methane. h, under the conditions of the target product yield up to 33.6%. The product was characterized by MS, IR, UV-Vis, 1HNMR, 19F NMR and EA. Under the excitation of 470 nm, the strongest emission peak of the compound was at 711 nm, which could be used as a potential luminescent material.
