Robust Metal–Organic Framework Containing Benzoselenadiazole for Highly Efficient Aerobic Cross-dehydrogenative Coupling Reactions under Visible Light
A zirconiumÂ(IV)-based
UiO-topological metal–organic framework (UiO-68Se) containing
benzoselenadiazole was synthesized by an approach of the mixed dicarboxylate
struts, which show highly efficient and recycalable photocatalytic
activity for aerobic cross-dehydrogenative coupling reactions between
tertiary amines and various carbon nucleophiles under visible-light
irradiation
Ratiometric Luminescent Detection of Organic Amines Due to the Induced Lactam–Lactim Tautomerization of Organic Linker in a Metal–Organic Framework
Here we demonstrate
that a fluorescent benzothiadiazole (BTD)-conjugated terphenyldicarboxylate
(TPDC) linker (denoted as H<sub>2</sub>-ostpdc) has been hybridized
by a quinoxaline-2,3-(1<i>H</i>,4<i>H</i>)-dione
(QD) moiety possessing lactam-lactim tautomerism, which was further
integrated into a robust and porous UiO-68 type zirconium metal–organic
framework (MOF UiO-68-osdm) by utilizing the mixed two dicarboxylate
struts with the same ligand lengths. The resultant MOF UiO-68-osdm
can work as a ratiometric luminescent sensor for visual and selective
detection of alkyl amines. Furthermore, it can discriminate secondary
alkylamines from other type amine species
Highly Efficient and Selective Photooxidation of Sulfur Mustard Simulant by a Triazolobenzothiadiazole-Moiety-Functionalized Metal–Organic Framework in Air
A photoactive triazolobenzothiadiazole
(TBTD)-conjugated terphenyldicarboxylate (TPDC) linker was introduced
into a porous and robust UiO-68 isoreticular zirconium metal–organic
framework (denoted as UiO-68-TBTD) by the de novo synthetic approach
of mixed TPDC struts. Under blue-light-emitting-diode irradiation,
UiO-68-TBTD can serve as a heterogeneous photocatalyst for the highly
efficient and selective oxidation of a sulfur mustard simulant (2-chloroethyl
ethyl sulfide) to the corresponding much less toxic sulfoxide product,
with a half-life of only 3 min in the open air atmosphere
