, p. 866 - 872 (2016)
The interplay of molecular rigidity enforced by interior or exterior hydrogen bonding and affinity for binding halide anions is described to demonstrate the effect of intramolecular hydrogen bonding in anion recognition process. To this end pyridine-2,6-d

Incorporation of specific functionalities within the framework offers a significant opportunity to produce high-performance gas storage/separation and catalysis MOF materials. In this work, multifunctionalities, including hydrophobic methoxy groups, polar acylamide functionalities, and open copper(II) sites, have been successfully integrated into a twofold interpenetrated microporous MOF (HNUST-6, HNUST represents Hunan University of Science and Technology). HNUST-6 possesses permanent porosity, with a moderate BET surface area of 1093 m2 g–1 and high CO2 adsorption capacity (111 cm3 g–1 at 1 bar), with good selectivity for CO2 over CH4 (6.6) and N2 (30.3) at 273 K. Remarkably, this MOF material exhibits excellent water stability and its framework structure is retained after being immersed in boiling water. In addition, HNUST-6 demonstrates efficient catalytic activity as a cooperative catalyst in a tandem one-pot deacetalization Knoevenagel condensation reaction.
Bispyrrolylbenzene anion receptor: From supramolecular switch to molecular logic gate

We have designed anion receptor 4 based on a conformationally labile bispyrrolylbenzene framework, the conformation of which can be changed by appropriate anionic stimuli. In the absence of fluoride anion, the pyrrole moieties rotate freely at room temperature. However, when the concentration of fluoride anion exceeds 2 equivalents, the rotation of the pyrrole units slows down and the conformation of the receptor changes to anti-anti. DFT calculations have shown that this change is due to binding of a third fluoride anion through C-H interaction. Anion receptor 4 can also serve as a molecular logic gate. Anionic inputs such as fluoride and dihydrogenphosphate allow the realization of INHIBIT and NAND logic gate functions with absorption and fluorescence as readouts, respectively.
