Abstract

Abstract : A microporous metal–organic framework, built from a silicon-centered linker that is among the never documented examples, exhibits a hollow tubular crystal morphology and displays turn-on and turn-off luminescence responses for n -butanol and acetone, respectively. Abstract : Solvothermal reaction of Cd 2+ cations with a silicon-centered carboxylic acid (H6 L) afforded a novel metal–organic framework, namely, [Cd3 L(H2 O)5 ]·DMA·H2 O (1 ). It is built from three {CdO6 } clusters and organosilicone linkers to form a 3D porous framework. The steric organosilicone ligand is among the never documented examples. Interestingly, 1 exhibited spontaneous formations of microtubular crystals, the phenomenon of which is rarely reported among the metal–organic coordination assemblies. In addition, the luminescence properties of1 dispersed in different organic solvents have been investigated, displaying turn-on and turn-off luminescence responses for n -butanol and acetone, respectively.
