Narrow thiophene-edged graphene nanoribbons (GNRs) were prepared from polychlorinated thiophene-containing poly(p-phenylene)s using the photochemical, metal-free cyclodehydrochlorination (CDHC) reaction. H NMR and Raman spectroscopy confirmed the structures of the GNRs. The regioselectivity of the CDHC reaction allows the preparation of both laterally symmetrical and unsymmetrical GNRs and, consequently, the modulation of their optical and electronic properties.
窄噻吩边缘石墨烯纳米带(GNRs)是通过使用光化学、无金属的环脱氢氯化(CDHC)反应,从含多氯噻吩的聚对亚苯基聚合物中制备的。1H NMR 和拉曼光谱证实了 GNRs 的结构。CDHC 反应的区域选择性允许制备具有对称和不对称的 GNRs,从而调节它们的光学和电子性质。
