A four-fold interpenetrated metal–organic framework as a fluorescent sensor for volatile organic compounds†
Abstract
A four-fold interpenetrated three dimensional (3D) metal–organic framework, [Cd2(tppe)(bpdc)2(H2O)]·solvent (1), was synthesized with a tetraphenylethene (TPE)-based ligand, 1,1,2,2-tetrakis(4-(pyridin-4-yl)phenyl)ethene (TPPE). This complex exhibits intense blue luminescence and is sensitive to toxic volatile organic compounds (VOCs).
