Summary: The application of new procedures in organometallic synthesis using alternative starting complexes has significantly enhanced the preparation of osmium(IV), osmium(II), and iridium(III) emitters since 2012. The choice of precursors should consider the ligands, as they play a role in emitter synthesis. Three different functions of ligands in the revised procedures have been identified, including directing selectivity in sigma-bond ruptures, participating in new coordinated groups, and acting as internal bases in activation reactions. Additionally, the ability of polyhydrides OsH6((PPr3)-Pr-i)(2) and IrH5((PPr3)-Pr-i)(2) to activate C-H bonds is highlighted as a key factor in the success of many cases.

Summary: A series of bis-metalated phosphorescent complexes were synthesized and characterized. The investigation of the complexes' spectroscopic properties and theoretical calculations revealed the importance of metal-to-ligand charge transfer and intraligand transition in the generation of emissive triplet states. The results showed systematic bathochromic shifts in the absorption and emission spectra upon insertion of electron-withdrawing substituents and expansion of the aromatic system. These findings provide valuable insights into the photophysical processes in complexes of this type and offer useful tools for fine-tuning their emissive characteristics.

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.
