Catalytic Activities

A convenient method for the preparation of imidazolium salts-functionalized mesoporous catalyst Me-Bmim-SBA-15 (2) by postgrafting [bmIm]OH on SBA-15 was developed. This catalyst presented excellent catalytic activities (more than 96% yields for all tested aldehydes) for Knoevenagel condensation of aldehydes and ethyl cyanoacetate under microwave irradiation in solid medium. Of particular note is that such a catalyst could be readily recovered and reused in the consecutively catalytic runs (up to 10 uses) while maintained high catalytic activity.

Three novel Zn-based coordination polymers (CPs), [Zn(MIPA)]n (1), {[Zn(MIPA)(4,4′-bipy)0.5(H2O)]·1.5H2O}n (2), and {[Zn(MIPA)(bpe)]·H2O}n (3) (MIPA = 4-methoxyisophthalic acid, 4,4′-bipy = 4,4′-bipyridine, bpe = (E)-1,2-di(pyridine-4-yl)ethane), were constructed by ligand 4-methoxyisophthalic acid under solvothermal conditions. Compound 1 features a beaded 2D-layer architecture, while compound 2 presents a 2-fold interpenetrating structure with a uninodal three-connected hcb topology. Compound 3 has a 3-fold interpenetrated four-connected dmp topology. Photoluminescence investigations of compound 2 were explored in detail, by which ions were detected, and it was observed to have the highest quenching efficiency toward Al3+ and S2− ions. The possible fluorescence quenching mechanisms of 2 toward Al3+ and S2− ions were also explored. To the best of our knowledge, this is the first potential dual-responsive luminescent probe based on a Zn(II) coordination polymer for detecting Al3+ and S2− ions via a luminescence quenching effect in ethanol.
