Synthesis of partial structural motifs of chiral graphene nanoribbons

石墨烯纳米带是一种很有前途的半导体材料。为了实现高质量的GNR合成，需要一种自底向上的方法。我们探索了以多环芳烃为原料制备手性纳米石墨烯材料的新方法，实现了（1）AuCl催化合成多环芳烃（PAHs）;（2）合成了一种新的多环芳烃原料，可作为手性GNR合成的候选原料;（3）合成了不含柔性取代基的可溶性T型双奥分子。

Graphene nanoribbons (GNRs) are promising future semiconductor materials. To achieve GNR synthesize with high quality, a bottom-up method is demanded. We explored new methodology to obtain chiral-type nanographene materials from simple starting polycyclic aromatic hydrocarbons.We achieved (1) synthesis of polycyclic aromatic hydrocarbons(PAHs) using AuCl catalyst, (2) synthesis of a new starting PAHs, which is a candidate for chiral-type GNR synthesis, (3) synthesis of the soluble T-shaped biazulene molecules without flexible substituents.
