We demonstrate the participation of cobalt in a photoinduced ligand-to-metal charge transfer process, which leads to the formation of ligand-based radical species and enables both homo and hetero cross-dehydrogenative coupling of indoles with decent yield at room temperature. This photo-induced LMCT process is substantiated by a series of mechanistic investigations.

Rare-earth-doped all-inorganic perovskite applications for near-infrared (NIR) emission are crucial for the construction of the next generation of intelligent lighting sources. However, the preparation of rare-earth-doped all-inorganic perovskite is complex, and difficult to control, and the issue of thermal quenching poses significant challenges to its practical application. Here, in order to address these issues, a convenient photo-induced synthesis method for CsPbCl:Mn/Yb nanocrystals (NCs) is proposed by decomposing carbon tetrachloride with 365 nm light to provide chloride ions and regulate the formation of perovskite at room temperature.

Chiral luminescent liquid crystal (LC) materials with switchable circularly polarized luminescence (CPL) signals have received extensive attention, in which the use of light stimulation to achieve different CPL states is of great significance. However, there are very few reports on the generation and regulation of CPL signals enabled by blue phase LC (BPLC). Herein, achieving CPL signal inversion based on the phase transition induced by light/temperature stimulation in a BPLC system with a wide room-temperature window is reported.

Hydroarylation reactions have emerged as a valuable tool for the direct functionalization of C-H bonds with ideal atom economy. However, common catalytic variants for these transformations largely require harsh reaction conditions, which often translate into reduced selectivites. In contrast, we herein report on a photo-induced hydroarylation of unactivated olefins at room temperature employing a readily available ruthenium(ii) catalyst.

We describe here the synthesis of ultrasmall Pt nanoparticles (NPs) obtained by a robust and reliable protocol using UV-Vis photoreduction of a platinum salt precursor, under continuous flow conditions. These ligand-free Pt NPs were rapidly dispersed onto a solid support or stabilized towards aggregation as a colloidal solution by the addition of an appropriate ligand in the reaction mixture. The proposed protocol exploits a microfluidic platform where the Pt precursor is photo-reduced to small Pt NPs (1.
