Nanobänder aus Helicen‐artigem Graphen (HGNRs) wurden durch regioselektive photochemische Cyclodehydrochlorierung eines polychlorierten Polyphenylens synthetisiert. In ihrer Zuschrift auf S. 6309 zeigen J.‐F. Morin et al., dass die HGNRs stark leuchten und im Vergleich zu anderen GNRs eine große Bandlücke aufweisen. Solche definierten helikalen GNR‐Strukturen bergen zahlreiche Anwendungsmöglichkeiten...
Graphene is a zero‐gap, semiconducting 2D material that exhibits outstanding charge‐transport properties. One way to open a band gap and make graphene useful as a semiconducting material is to confine the electron delocalization in one dimension through the preparation of graphene nanoribbons (GNR). Although several methods have been reported so far, solution‐phase, bottom‐up synthesis is the most...
