Summary: The photophysical properties of a series of NIR-emitting iridium complexes were studied, and it was found that their characteristics are mainly determined by the properties of the metalating ligands. These complexes showed lower oxygen-quenching constants and acceptable cytotoxicity in physiological media. Additionally, they can be used for semi-quantitative measurement of oxygen concentration in living cells.

Summary: A comparative study of the luminescence properties of solutions and crystals of two isomers has revealed an interrelation between the molecular and crystal structure and their luminescence properties. The differences in luminescence properties of the crystals were attributed to their abilities to form excimers. Additionally, delayed fluorescence was observed in the crystals and solutions of one isomer at 77 K.

Summary: The orientation of facial tris-cyclometalated iridium complexes in doped films can be controlled by altering the physical shape and electronic asymmetry in the molecular structure. Oblate iridium complexes have a net horizontal alignment in the thin films due to favorable van der Waals interaction with the host material, while chemical asymmetries introduced by substituents affect the oblate shapes and orientation of the molecules. The fluorinated patches in the substituted derivatives reinforce horizontal alignment during deposition, resulting in improved efficiency in organic light emitting diodes.

Summary: This study evaluated four different detection platforms for phosphorescence lifetime (PLT) measurements. The results showed that the Victor 2 fluorescence reader produced stable but inaccurate readings at low PLT values, while the Cary Eclipse luminescence spectrometer was able to partly correct this issue. The Tpx3Cam camera-based macroscope and the confocal laser-scanning FLIM/PLIM microscope provided more accurate and informative PLT data.

Summary: This work describes the synthesis and characterization of a series of neutral Chugaev-type chelating dicarbene iridium complexes with different cyclometalating ligands. The effects of these ligands on the emission properties of the complexes are evaluated, and it is found that the complexes exhibit blue-shifted phosphorescence compared to previously described analogues. The study also investigates the electrochemical properties of the compounds and determines the dependence of HOMO and LUMO energies on the cyclometalating ligands.

Summary: A robust aqueous solid-electrolyte interphase (SEI) is successfully constructed by introducing a ladderized heterocyclic polymer electrode into a water-in-salt electrolyte, enabling ultra-stable dual-ion storage with long-term calendar life. The sophisticated SEI composed of fluorinated/oxygenated species is formed through a proton co-intercalation process, consuming water in the solvation shell of Li+ ions to trigger the decomposition of organic anions. This new SEI formation path is expected to broaden the applications of aqueous SEI and facilitate the design of versatile electrode materials for advanced aqueous Li-ion batteries (ALIBs).
