以三苯三戊并烯或窗茚满为核心的非平面纳米石墨烯

Nonplanar Nanographenes Based on Tribenzotriquinacene or Fenestrindane Core

总结了我们近年合成的以三苯三戊并烯或窗茚满为骨架的非平面纳米石墨烯之研究成果.巫师帽形或鞍形的纳米石墨烯可由非经典的Scholl环庚三烯环化或19元环大环化反应制备.这些反应成功的关键是在这些分子的湾区区域引入恰当的富电子芳香官能团,通过X射线晶体学,一些纳米石墨烯的三维结构可以得到确定.此外,这些富含碳的π-共轭分子还显示出有趣的光物理、自缔合和主-客体络合的特性.

Our recent research efforts on the synthesis of nonplanar nanographenes bearing tribenzotriquinacene or fenestrindane skeleton are summarized.Wizard hat-shaped or saddle-shaped nanographenes could be prepared using a non-classical Scholl-type cycloheptatriene formation or 19-membered ring macrocyclization.The key to the success of these transformation relies on the proper installation of the electron rich aryl functional groups in the bay areas of these molecular motifs.The three-dimensional structures of some of the nanographenes were determined by X-ray crystallography.Furthermore,these carbon-richπ-conjugated molecules are also showed to have interesting photophysical,self-assoication and host-guest complexation properties.
