Porous curved polycyclic aromatic compounds 6 and 14 bearing a tribenzotriquinacene (TBTQ) core encircled by an m,p,p,m,m,p,p,m,m,p,p,m‐cyclododecaphenylene belt were synthesized and characterized by NMR spectroscopy and mass spectrometry. These trefoil hydrocarbon macrocycles were constructed in high yield using an intramolecular three‐fold Scholl macrocyclization. X‐ray crystal analysis of 14 demonstrated
合成了由m,p,p,m,m,m,p,p,m,m,p,p,m环十二碳联苯带环绕的带有三苯并三喹并苯(TBTQ)核的多孔弯曲多环芳族化合物6和14光谱学和质谱学。这些三叶烃大环化合物是使用分子内三倍Scholl大环化技术高收率构建的。X射线晶体分析显示14个具有三个孔(半径2.9-3.0Å)的大向导帽形结构。六正十二烷基氧基衍生物6 a的π堆积聚集和14的氯阴离子结合特性通过NMR光谱进行了研究。这样的堆积和阴离子结合特性在单个11和双大环化产物12中要弱得多。
