In this article, we describe our chemical approach, developed over the course of a decade,
towards the bottom‐up synthesis of structurally well‐defined graphene nanoribbons (GNRs) …

Graphene nanoribbons display extraordinary optical properties due to one-dimensional
quantum-confinement, such as width-dependent bandgap and strong electron–hole …

Carbon nanomaterials are expected to be bright and efficient emitters, but structural
disorder, intermolecular interactions and the intrinsic presence of dark states suppress their …

The precise bottom‐up synthesis of graphene nanoribbons (GNRs) with controlled width
and edge structures may compensate for graphene's limitations, such as the absence of an …

Abstract The Diels–Alder reaction has been widely used in synthetic organic chemistry since
its discovery in 1928. The catalyst-free nature, functional group tolerance and high efficiency …

Excitons play a key role in technological applications since they have a strong influence on
