Modulating Photo- and Radioluminescence in Tb(III) Cluster-Based Metal–Organic Frameworks

Luminescent metal–organic frameworks (MOFs) are of interest for sensing, theranostics, dosimetry, and other applications. The use of lanthanoids in MOF metal nodes allows for intrinsic met-al-based luminescence. In this work, a facile route for modulat-ing the photoluminescent and radioluminescent properties of Tb(III)-based MOFs is reported. By using Tb(III)-cluster nodes as X-ray attenuators, and organic linkers with varying excited state energies as sensitizers, MOFs with metal-based, linker-based, and metal+linker-based photo- and radioluminescence are reported.

Intermolecular Nucleophilic Addition Reaction of C-7 Anions from N-bis(dimethylamino)phosphinoyl Indoles to Electrophiles/Arynes: Synthesis of 7-Substituted Indoles.

A novel approach for C-7 substitution of N-bis(dimethylamino)phosphinoyl indole by nucleophilic addition of C-7 carbanion to electrophiles and arynes is described and the directing group can be easily removed which provides a facile route for synthesis of 7-functionalized indoles.
