Nanocage-based {In2Tm2}-organic framework for efficiently catalyzing the cycloaddition reaction of CO2 with epoxides and Knoevenagel condensation

The combination of [In2Tm22-OH)2(CO2)10(H2O)2] clusters and H5BDCP ligand generated a highly robust nanoporous MOF with high catalytic performance in the cycloaddition reaction of epoxides with CO2 and Knoevenagel condensation.

Decisive role of non-rare earth metals in high-regioselectivity addition of μ3-carbido clusterfullerene

The reaction of μ3-CCF Dy2TiC@Ih-C80 with AdN2 affords only one [6,6]-open monoadduct along with the addition sites adjacent to the Ti4+ ion instead of the two Dy3+ ions, revealing the decisive role of the non-rare earth metal Ti(IV).

Enhancing photoluminescence efficiency of atomically precise copper(I) nanoclusters through a solvent-induced structural transformation

Atomically precise alkynyl-protected copper(I) nanoclusters (CuNCs) have been prepared, and they exhibit high phosphorescence quantum yield, short lifetime, and fast radiative decay rate, which are rarely observed in atomically precise CuNCs.
