Fluorescent metal–organic framework based on pyrene chromophore for sensing of nitrobenzene

A novel 3D MOF constructed by a dendritic ligand with pyrene chromophore and Mg was synthesized. The MOF shows specific fluorescence response to DMF and can sense nitrobenzene at a low detection level, making this a promising material for detecting explosive substances.

Stepwise radial complexation from the outer layer to the inner layer of a dendritic ligand: a phenylazomethine dendrimer with an inverted coordination sequence

A meta-substituted phenylazomethine dendrimer was discovered as a dendritic ligand that sequentially coordinates to Lewis acids from the outer layer to the inner layer in a stepwise radial fashion.
