Toward Electronic Materials Based on Metal Pincer-Type Complexes

TL;DRAbstract

There is currently a lot of interest in developing electrically conducting or semiconducting metal-organic frameworks (MOF's), highly porous materials constructed by organic ligands bridging metal centers. Typically MOF's are non-conducting and, moreover, they are susceptible to hydrolytic degradation. If hydrolytically stable and electrically conducting MOFs could be realized, then revolutionary new technologies could be envisioned. Currently, organic dicarboxylates are used as bridging organic ligands and one simple strategy to obtain the desired materials is to explore other ligand systems. Pincer ligands are organic compounds that are uninegative and bind metals in a tridentate, meridional fashion with two five-member chelate rings. There is intense contemporary interest in studying metal complexes of these pincer- or pincer-type ligands (variants with six-membered chelate rings) because they can exhibit remarkable stability and they can often promote unusual chemical transformatio
