A new Cd(II)-based metal–organic framework for highly sensitive fluorescence sensing of nitrobenzene

A Cd(II)-based metal–organic framework, {[Cd2L(H2O)2]·DMF·H2O}n (1), has been successfully constructed from a new flexible antler-like multidentate ditopic ligand (H4L). This metal–organic framework shows highly sensitive fluorescence sensing of nitrobenzene.

A viologen-based coordination polymer exhibiting high sensitivity towards various light sources

The self-assembly of a photoactive 1,1′-bis(4-carboxybenzyl)-4,4′-bipyridinium ligand with cadmium chloride in the presence of a strong electron-donating oxalate anion has successfully afforded a photochromic coordination polymer, which shows high sensitivity not only to ultraviolet-visible radiation but also to X-rays.

Coexistence of self- and interpenetration in two (3,6)-connected porous coordination polymers

Two isostructural (3,6)-connected porous coordination polymers topologically featuring both self- and interpenetration have been successfully synthesized. The porous material shows a reversible crystalline-to-amorphous transition associated with the removal and recapture of guest molecules. Particularly, the porous material demonstrates selective detection of nitrobenzene through fluorescence quenching.
