Summary: The photo- and electrochemical properties of a novel cymantrenyl-containing phthalimide were investigated using various techniques such as cyclic voltammetry, FTIR, H-1 NMR, UV-vis, and fluorescence spectral methods. The results revealed that the initial tricarbonyl complex released a CO ligand upon irradiation, forming a colored dicarbonyl chelate, which could be reversed to the initial tricarbonyl complex in the presence of CO. Moreover, the introduction of a cymantrenyl group in the phthalimide molecule significantly affected the absorption and emission spectra, as well as the electrochemical properties. These findings suggest that this type of compound holds great potential for the development of photo- and electroactive materials, as well as exciplex-forming materials.

Summary: In this study, a variety of macrocycles containing different types of porphyrins were examined in twenty different solvents using electronic absorption spectroscopy. The results showed that the presence of various substituents and different solvents influenced the absorption spectral properties of the macrocycles. The red-shift in absorption bands of mixed substituted porphyrins in polar solvents was attributed to solvent-core interactions and the electronic nature of the macrocycle.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
