摘要
以四苯基环戊二烯酮和1,4-二苯乙炔基苯为原料,通过Diels-Alder加成反应合成了1,4-二(2,3,4,5,6-五苯基苯基)苯,进一步在CuCl2/AlCl3作用下脱氢环化制备了石墨烯结构的二维聚苯,并通过红外光谱、紫外光谱、核磁共振氢谱和元素分析对其结构进行了表征。研究了上述化合物的热稳定性和发光特性,结果表明,这两种化合物的分解温度都大于450℃,热稳定性较好。1,4-二(2,3,4,5,6-五苯基苯基)苯和石墨烯结构的二维聚苯的荧光发光波长分别在349.2 nm和487 nm处。
1,4-（ 2,3,4,5,6 -Pentaphenylphenyl）benzene was synthesized by Diels-Alder reaction with tetraphenylcyclopentadienone and 1,4- bis（phenylethynyl） benzene. Two-dimensional polyphenylene with graphene structure was prepared through the dehydroeyelization of 1,4 -（ 2,3,4,5,6 - Pentaphenylphenyl） benzene at presence of CuCl2 and AlCl3. The as-synthesized compounds were characterized by FT-IR, UV-Vis, ^1H NMR spectroscopy and elemental analysis. Thermogravimetric analysis shows that the as-synthesized compounds have excellent thermal stability with the decomposition temperature being above 450 ℃. Fluorescence spectra show that the maximum fluorescence wavelength of 1,4 - （ 2,3,4,5,6 - Pentaphenylphenyl） benzene and two-dimensional polyphenylene is 349.2 nm and 487 nm respectively.
