Fluorescence detection of Mn2+, Cr2O72− and nitroexplosives and photocatalytic degradation of methyl violet and rhodamine B based on two stable metal–organic frameworks. Issue 17 (7th February 2017) - Wu, Yu
Abstract : Two new MOFs show 3D 2-fold interpenetrating 4-connected networks and could be a prospective candidate for developing the luminescence sensors and the photocatalysis due to their highly stabilities. Abstract : The reaction of Zn(NO3 )2 ·6H2 O/Cd(NO3 )2 ·4H2 O with a semi-flexible ligand 4′-(4-(3, 5-dicarboxylphenoxy)phenyl)-4, 2′:6′, 4′′-terpyridine (H2 dbp) gave two new metal–organic frameworks of [Zn(dbp)] n (1 ) and [Cd(dbp)(H2 O)·2H2 O·CH3 CN] n (2 ). Single crystal X-ray diffraction analyses reveal that both 1 and 2 show three-dimensional, two-fold interpenetrating four-connected networks with 4 4 .6 10 .8 topology. The photoluminescence investigation indicates that both 1 and 2 could be prospective candidates for developing luminescence sensors for the sensing of Mn 2+, Cr2 O7 2− and nitroaromatic analytes. Furthermore, the photocatalysis properties of 1–2 for the degradation of methyl violet and rhodamine B were examined.
