Metal–organic framework composites with luminescent pincer platinum(ii) complexes: (3)MMLCT emission and photoinduced dehydrogenation catalysis

Pincer platinum(ii) complexes are well documented to exhibit weak intermolecular interactions in the solid state and 77 K glassy solutions, leading to emissive triplet metal–metal-to-ligand charge transfer ((3)MMLCT) excited states that often vanish in dilute solutions. In this work, metal–organic f...

Sumario:Pincer platinum(ii) complexes are well documented to exhibit weak intermolecular interactions in the solid state and 77 K glassy solutions, leading to emissive triplet metal–metal-to-ligand charge transfer ((3)MMLCT) excited states that often vanish in dilute solutions. In this work, metal–organic framework (MOF) materials are introduced to provide a “solid solution” environment for easy access to (3)MMLCT excited states of pincer platinum(ii) complexes. Phosphorescent composites Pt(II)@MOFs (1–4) with matrix-dependent monomers and oligomer emission properties were obtained. These Pt(II)@MOFs are efficient catalysts for photoinduced dehydrogenation reactions.
