An anionic Cd(ii) boron imidazolate framework with reversible structural transformation and biomolecular sensing properties

An anionic Cd(ii) boron imidazolate framework (BIF-82) with gra topology has been synthesized by the targeted assembly of Cd(ii), the 1,3,5-benzenetricarboxylate ligand and the tetradentate boron imidazolate ligand, which shows reversible structural transformation, and it can encapsulate Ag nanoparticles into its structure for further sensing of cysteine.
