Here, a straightforward and rational approach to construct supramolecular assemblies with ordered nanostructures in a two-dimensional arrangement is reported. Taking advantage of the synergistic effect of multiple non-covalent interactions (hydrogen bonding and π-π interactions), the designed molecular monomer has a specific orientation in the self-assembly process, thus realizing two-dimensional control. Supramolecular two-dimensional nanosheets with single-layer thickness and controllable dimensions have been obtained, which can be clearly confirmed using TEM, SEM, AFM and XRD and by comparing with the self-assembled structures of the control system. The strategy of collaborative self-assembly proposed here using multiple non-covalent interactions is expected to be extended to the construction of various kinds of unique supramolecular 2D materials.

A series of 2,5-substituent hydroquinone derivatives were designed and synthesized. Their structures were identified by elemental analysis, 1H NMR, IR spectra. Their assayed antibacterial (Escherichia coli, Bacillus subtilis) and antifungal (Candida albicans) activities were also evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method. The results of biological test showed compounds 1 and 10 have favorable antimicrobial activity with MICs of 20.5, 24.6, 18.9 and 28.6 μg/mL against Escherichia coli and Bacillus subtilis, respectively.

The modification of metal-organic frameworks (MOFs) by functionalizing ligands has been investigated for improved properties. In this study, by introducing substituents to the backbone of organic linkers, isostructural dihydroxy-/dialkoxy-functionalized Zr-MOFs were delicately constructed and sophisticatedly characterized for crystallinity, morphology, porosity and structural defects. Pure-component CO2, CH4, N2, and H2adsorption isotherms on the microporous synthesized materials were investigated under the pressure up to 10 MPa at 303 K. By the ideal adsorbed solution theory (IAST) model, enhanced adsorption selectivity towards CO2/N2, CO2/CH4, CH4/N2and CO2/H2binary mixtures was observed compared to the parent material, and dihydroxy functionalization endows the material with high selectivity towards CO2/H2. Moreover, the diethoxy-functionalized material with narrow cavities exhibits improved high pressure H2adsorption due to structural defects and strong overlapping potentials.
