Novel poly-NHC

Some additional reports on novel and/or interesting types of poly-NHC hgand architectures have appeared in the recent literature (Fig. 9). 

Investigations on the chemistry of poly-NHC metal complexes have of course not been hmited to the preparation of complexes with novel features and properties, as extensively outlined above, but have also heavily involved their apphcations. Catalysis has long been the main field in which the use of these complexes was envisaged, but in more recent years, other applications of poly-NHC metal complexes have been identified and pursued with a notable degree of success. Besides catalysis, today there are at least two other main appHcation areas of these complexes, namely their use as emissive moieties in the development of photo- or electroluminescent devices, and as bioactive compounds, typically with antimicrobial or anti-tumoral properties the following sections will extensively cover the recent advances in these fields.
