以四苯基环戊二烯酮和二苯乙炔衍生物为原料,在高温下(250~300℃)通过Diels-Alder加成反应合成了六苯基苯(HPB)和(4-溴苯基)五苯基苯(HPB—Br),进一步采用氯化铜和无水氯化铝为催化剂室温下在二硫化碳溶剂中脱氢环化获得标题化合物,并通过红外光谱、紫外-可见吸收光谱、核磁共振氢谱和元素分析对产物的结构进行了表征。热重分析表明,六苯并蔻类化合物具有较高的热稳定性;荧光光谱表明,六苯并蔻(HBC)和单溴代六苯并蔻(HBC—Br)的发光光谱都具有清晰的精细结构,最大发射峰位置分别在482.2和482.8nm处。
Hexaphenyl benzene (HPB) and (4-bromophenyl) benzene were synthesized by Diels-Alder reaction at high temperature (250-300 ℃) using tetraphenylcyclopentadienone and the derivatives of p- ) Pentabenzene (HPB-Br). The title compound was further dehydrocyclized in carbon disulfide solvent at room temperature using cupric chloride and anhydrous aluminum chloride as catalysts. The compounds were characterized by IR, UV-Vis, Resonance hydrogenation and elemental analysis of the product structure was characterized. Thermogravimetric analysis showed that the hexabenzofuko compounds have high thermal stability. Fluorescence spectra showed that the emission spectrum of both hexabromobenzene (HBC) and monobromohexabromobenchol (HBC-Br) Fine structure, the maximum emission peak position at 482.2 and 482.8nm at.
