AbstractNanographenes are emerging as a distinctive class of functional materials for electronic and optical devices. It is of remarkable significance to enrich the precise synthetic chemistry for these molecules. Herein, we develop a facile strategy to recompose helicenes into chiral nanographenes through a unique oxidative cyclo-rearrangement reaction. Helicenes with 7~9 ortho-fused aromatic rings are firstly oxidized and cyclized, and subsequently rearranged into nanographenes with an unsymmetrical helicoid shape through sequential 1,2-migrations. Such skeletal reconstruction is virtually driven by the gradual release of the strain of the highly distorted helicene skeleton. Importantly, the chirality of the helicene precursor can be integrally inherited by the resulting nanographene. Thus, a series of chiral nanographenes are prepared from a variety of carbohelicenes and heterohelicenes. Moreover, such cyclo-rearrangement reaction can be sequentially or simultaneously associated with conventional oxidative cyclization reactions to ulteriorly enrich the geometry diversity of nanographenes, aiming at innovative properties.

Intense Activity

In recent years, visible-light-mediated copper photocatalysis have emerged as an attractive strategy for the diverse constructions of basic bonds in an ecologically benign and cost-effective fashion. The intense activity and increasing work of these areas stimulated the exploit of the distinctive properties of copper photocatalysis and the rapid development and expansion of their applications. In this review, we focus on introducing a series of significant achievements in copper complexes as standalone photocatalysis in organic reactions to make an attempt to exhibit their potential capabilities and high flexibilities in synthetic chemistry.
