Metal-Based Multihelicenic Architectures

Abstract

The preparation of multihelicenic systems by conventional organic synthesis is a challenging task and under continuous development. In parallel, using complexing units grafted to or incorporated within the helicene core and taking advantage of coordination/organometallic chemistry constitutes a powerful strategy to obtain multihelicenic structures. This Minireview focuses on the state-of-the-art preparation of metal-based multihelicenic architectures such as coordination-driven supramolecular assemblies and organometallic architectures. Their properties and their applications are presented.

Keywords: chirality; chiroptical activity; coordination assemblies; multihelicenic complexes; organometallics.
