Bis(imidazolylidene)s as modular building blocks for monomeric and macromolecular organometallic materials.
The synthetic and structural progression surrounding N-heterocyclic carbenes has given rise to great functional and architectural diversity in organometallic chemistry, catalysis, and materials science. The development of new, modular scaffolds for bridging transition metals is essential in order to expand the boundaries of these scientific areas. This Frontier article summarizes recent advances in the synthesis and study of ditopic ligands displaying two linearly opposed carbene moieties and emphasizes their versatility in the preparation of new organometallic and macromolecular materials. The conclusion previews their utility in conjugated organic/inorganic hybrid materials with potential applications in the emerging fields of molecular- and nanoelectronics.
