Summary: A multi-responsive receptor consisting of two (acridinium-Zn(II) porphyrin) conjugates has been designed, showing eight states resulting from the cascade of recognition and responsive events. The binding constant between the receptor and a ditopic guest can be modulated by the addition of nucleophiles and oxidation of the porphyrin units. The acridinium/acridane conversion leads to a significant change in the photophysical properties, with a switch from electron to energy transfer processes. Interestingly, charge-transfer luminescence in the near-infrared has been observed for the bis(acridinium-Zn(II) porphyrin) receptor.

Summary: This study describes a series of conformationally rigid (Zn-salphen)(2) complexes with potential enhanced catalytic activity for the coupling of CO2 with epoxides by fine-tuning the intermetallic separation and geometry. Some dibenzofuran derivatives exhibit significantly higher activity for the production of cyclic carbonate compared to their mononuclear analogues under identical conditions. Experimental results provide strong evidence of cooperative reactivity in these Zn-2 catalysts.

Summary: In this study, four new metallophosphonates were synthesized and their structures, magnetic properties, and optical properties were investigated experimentally and theoretically. These compounds have complex molecular structures and layered structures, exhibit dominant antiferromagnetic interactions, and show optical properties influenced by both the ligand and transition metals.

Summary: The synthesis and photophysical properties of bis-cyclometalated halido(aryl) Pt(iv) complexes are reported. The introduction of aryl ligands through different methods and the comparison of chlorido and fluorido derivatives in terms of emission lifetimes and radiative rate constants are discussed. The study also highlights the role of radical species in the activation of solvents during the oxidative addition reaction.

Summary: In this study, two NIR luminescent Zn(II)/Cd(II)-Yb(III) complexes were synthesized using a Schiff base ligand with a binaphthyl backbone. The Cd(II)-Yb(III) complex 2, with a triangular structure, showed interesting luminescent sensing activity towards antibiotics CPFX and NFX, unaffected by the presence of other antibiotics tested.

Summary: The efficiency of interfacial charge transfer for metal-tetraphenylporphyrins (M-TPPs) on rutile TiO2(110) depends on the molecular adsorption site and configuration. M(II)-TPPs with M = Co, Ni, Cu, Zn adsorb on the O-br rows with the same molecular conformation and form a commensurate phase with the same symmetry. The tendency to axial coordination determines the molecular adsorption energy and the preference for adsorption atop one O-br atom or on a bridge between two O-br atoms.
