Resumen:

This chapter provides an overview of the latest advances on the use of d8 metal-based pincer complexes for optical chemosensing/recognition of relevant analytes, made post-2007. The field is active and constantly growing, however, there are still many potential applications focused on molecular recognition studies that remain largely unexplored in comparison to historical applications, such as catalysis for organic transformations, and to a lesser extent, as luminescent biomarkers for proteins and phosphorescent compounds for new materials. The present work provides a structural approach describing luminescent and chromogenic sensing properties of divalent pincer complexes of Pt, Pd, and Ni containing terpyridine (N^N^N), rigid mer-tridentate (N^C^N), and bisphosphinite (P^C^P) chelating-ligands for the recognition of inorganic/organic anions, biologically relevant anionic species such as nucleotides and proteins, pollutant transition metals, and chemical compounds. Moreover, their potential implications for diverse scientific fields are also discussed. Metal-based pincer compounds with outstanding photophysical properties and potential binding sites for specific guests have emerged through the past few years as a new and interesting approach to breaking the limit of affinity and sensing of typical molecular sensors in competitive media as polar organic solvents and aqueous media. © 2018 Elsevier Inc.
