“…Structure-directing agents (SDAs) are becoming an active research area today, particularly in the fields of zeolite or molecular sieve syntheses. − SDAs seldom appear in the final backbone of architectures but act as templates, space-filling molecules, or counterions for charge balance in the pores. − Commonly used SDAs include organic/inorganic acids, polyoxometalatic acids, organic amines, and solvent molecules. − Recently, SDAs began to be employed for the preparation of coordination polymers (CPs). , By analyzing previous works, we found that rational utilization of SDAs could result in different structures upon adjustment of the dimensions of CPs. − …”

Herein, in the presence of three structure-directing agents (SDAs), a family of imidazole-functionalized resorcin[4]arenebased coordination polymers (CPs), [Zn(TIC4R)(HCOO)]•HCOO• 0.5DMF•1.5H 2 O (1), [Zn(TIC4R)(CN)]•HCOO•DMF•2.5H 2 O (2), and [Zn(TIC4R)(H 2 O)]•2HCOO•2H 2 O (3), were assembled under solvothermal conditions [TIC4R = tetra(imidazole) resorcin[4]arene].1 exhibits a double-layer structure with rectangle windows, and 2 and 3 display monolayer structures. The layers of CPs 2 and 3 are slides with different offsets along the a-axis. In addition, three CPs were used as catalysts to catalyze Knoevenagel condensations. Strikingly, all CPs exhibit remarkable catalytic performance for several substrates. To the best of our knowledge, this is the first time that a small organic acid as SDA was used in the syntheses of resorcin[4]arene-based supramolecular isomers.

Studies on the Genesis and Proton Conductivity of Imidazole-Based Linear and Open-Framework Zinc Phosphites

et al. 2021

Three new zinc phosphites, [HIm]2[Zn3(HPO3)4] (1), [Zn2(HPO3)2Im2] (2), and [Zn(HPO3)Im] (3) (Im = imidazole), have been synthesized from the hydro/solvothermal reaction of zinc acetate, dimethyl phosphite, and imidazole by varying the temperature and solvent of the reaction medium. The structure of 1 is built from vertex-sharing of four HPO3-capped Zn3P3 units and adopts an open framework with 12-ring channels stabilized by HIm cations via N–H···O hydrogen bonds. For 2, the inorganic skeleton is comprised of alternating ZnO4 and HPO3 tetrahedra, while the coordinatively associated ZnN2O2 fragments occupy the 12-ring hexagonal channels. Compound 3 adopts a ladder-type one-dimensional structure and exhibits N–H···O hydrogen-bonding interactions to afford a supramolecular assembly. A plausible rationale on the genesis of 1–3 has been put forth by reacting the preformed inorganic zinc phosphites Zn{OP(O)(OMe)H}2 or [Zn2(HPO3)2(H2O)4]·H2O with imidazole as the structure-directing ligand. Alternating-current impedance measurements reveal that 1 and 3 exhibit proton conductivities on the order of 10–3–10–4 S cm–1 between 25 and 100 °C under 35 and 77% relative humidity in repeated impedance cycles (E a = 0.22–0.35 eV). On the contrary, the conduction property is completely impaired in 2 under similar conditions.

Pillared-layered indium phosphites templated by amino acids: isoreticular structures, water stability, and fluorescence

Abstract: Two crystalline open-framework indium phosphites (denoted SCU-31 and SCU-32) were prepared using amino acids as structure-directing agents. They have isoreticular pillared-layered structures built up from 6*1 and 4=1 clusters. Notably,...
