Photolysis of 1,1′-(1,8-naphthylene)-bis(1H-1,2,3-triazole)s (1) in methanol has given new heteroaromatic system compounds, indolo[6,7-g]indoles (2). The spectral properties of these compounds were studied in comparison with those of the corresponding benz[g]indoles (4) obtained from the similar photolysis of 1-(1-naphthyl)-1H-1,2,3-triazoles (3). The 1H NMR and IR spectra of 2 and 4 suggest the existence
1,1'-(1,8-萘)-双(1H-1,2,3-三唑)s (1) 在甲醇中的光解产生了新的杂芳族系统化合物,吲哚[6,7-g]吲哚( 2)。将这些化合物的光谱特性与从 1-(1-萘基)-1H-1,2,3-三唑 (3) 的类似光解获得的相应苯并 [g] 吲哚 (4) 的光谱特性进行比较研究。2和4的1H NMR和IR谱表明2中存在强分子内氢键。四乙基1H,10H-吲哚[6,7-g]吲哚-2,3,8的X射线晶体分析, 9-四羧基后期,2a,表明该分子具有几乎两倍的旋转对称性,并且由于空间过度拥挤导致框架扭曲。
