Robust Passivation of Perovskite Using Rubidium Iodide for Efficient Photovoltaic Applications under Various Illumination Environments

open access: yesSmall Structures, EarlyView.
A robust defect passivation strategy for perovskite films using rubidium iodide (RbI) is reported. The RbI treatment simultaneously mitigates defects across the buried interface, within the bulk, and on the surface of perovskite films. This enhances crystallinity, suppresses ion migration, and reduces phase segregation.

Recent Synthetic Advances in C–H/N–H Functionalization of 1H‐Pyrazoles: Diverse Strategies Across Variously Substituted Scaffolds

open access: yesThe Chemical Record, EarlyView.
Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...

Characterizing Gallium Dinitridocarbonates: A Focus on LiGa(CN2)2, Li13.6Ga2.8(CN2)10I2, and SrGa2(CN2)4

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Three ternary gallium carbodiimides were synthesized via solid‐state metathesis reaction. The stable compound SrGa2(CN2)4 is showing a band gap in the order of 3 eV, LiGa(CN2)2 represents a carbodiimide‐cyanamide and Li13.6Ga2.8(CN2)10I2 contains disordered lithium ions.

Two Polymorphs of the Magnetic Catena‐Orthoperiodato‐Cuprate(II) K3[CuIO6]·4H2O from Ultra‐Alkaline Media

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The ultra‐alkaline condition of a hydroflux facilitate the synthesis of a new periodato cuprate(II). Fully deprotonated orthoperiodate octahedra are connected into chains by copper(II) cations. The two modifications differ in the constitution of these chains, which influences the magnetism of the compounds.
