Three-dimensional photoluminescent pillared metal-organic framework with 4.82 topological channels obtained from the assembly of cadmium(ii) acetate and trimellitic salt

Abstract

Reaction of the piperidinium salt of trimellitic acid (BTC³⁻) with cadmium(II) acetate dihydrate yields an unprecedented 3D pillared metal-organic framework, [Cd₃(BTC)₂(H₂O)₆]·3H₂O, showing strong blue luminescence. The framework contains 4.8² topological channels, in which the ‘floors’ are directly connected by the pillars of the BTC³⁻ benzene rings.
