connected into a three-dimensional (3D) supramolecular structure by hydrogen bonds. In complex 2, π···π stacking interaction is observed. In contrast, 3 shows a ion-pair structure, which is connected into a 2D 44 hydrogenbonded supramolecular structure. The results indicate the subtle difference of azamacrocycle may lead to diverse structures. Importantly, in complexes 1–3, the resonance structure is

Abstract The design, synthesis, and characterization of a star shaped 2,4,6-tris-(4`-carboxyphenoxy)-1,3,5-triazine liquid crystalline with columnar discotic mesophase properties establish H-bond interactions with 3,5-dialkoxypyidine were reported. The structures of the synthesized compounds were actually determined by elementary analysis, and FT-IR, 1HNMR, 13CNMR, and mass spectroscopy. The mesomorphic

A hydrothermally stable MOF, [Zn2(tcpt)OH]·solvents (1·solvents), was synthesized, in which an unusual paddlewheel SBU, Zn2(COO)3, was found. Furthermore, 1 can adsorb considerable amounts of H2 and displays high selective adsorption of CO2 over N2.
