a Por-GNR hybrid, which consists of two Pors connected by a short GNR segment. The atomically precise structure of the Por-GNR hybrid has been characterized by bond-resolved scanning tunneling microscopy (STM) and noncontact atomic force microscopy (nc-AFM). The electronic properties have been investigated by scanning tunneling spectroscopy (STS), in combination with DFT calculations, which reveals
表面合成为制备新型的碳基纳米结构提供了一种通用的方法,而这些是常规溶液化学无法获得的。石墨烯纳米带(GNR)具有多种应用潜力。它们在分子电子学中应用的关键问题是通过结构修饰(例如杂原子掺杂或引入非苯环)来微调其电子性能。在这种情况下,GNR和卟啉(Pors)的共价融合是一种极具吸引力的策略。在本文中,我们介绍了Por-GNR杂种的选择性表面合成,该杂种由通过短GNR片段连接的两个Pors组成。Por-GNR杂化物的原子精确结构已通过键分辨扫描隧道显微镜(STM)和非接触原子力显微镜(nc-AFM)进行了表征。
