Nanofibrils of a Cu-Thiophenyltriazine-Based Porous Polymer: A Diverse Heterogeneous Nanocatalyst.

Herein, we report knitting of a thiophenyltriazine-based porous organic polymer (TTPOP) with high surface area and high abundance of nitrogen and sulfur sites, synthesized through a simple one-step Friedel-Crafts reaction of 2,4,6-tri(thiophen-2-yl)-1,3,5-triazine and formaldehyde dimethyl acetal in the presence of anhydrous FeCl, and thereafter grafting of Cu(OAc)·HO in the porous polymer framework to achieve the potential catalyst (Cu-TTPOP). TTPOP and Cu-TTPOP were characterized thoroughly utilizing solid-state C-CP MAS NMR, Fourier transform infrared, wide-angle powder X-ray diffraction, thermogravimetric analysis, and X-ray photoelectron spectroscopy and surface imaging by transmission electron microscopy and field emission scanning electron microscopy. The porosity of the nanomaterials was observed in the surface imaging and verified through conducting N gas adsorption techniques.

A new benzimidazole based covalent organic polymer having high energy storage capacity.

We report the synthesis of a new benzimidazole-based covalent organic polymer (TpDAB) via solvothermal Schiff base condensation between 1,3,5-triformylphloroglucinol (Tp) and 3,3'-diaminobenzidine (DAB). TpDAB showed high energy storage capacity with a specific capacitance of 335 F g(-1) at 2 mV s(-1) scan rate and good cyclic stability with 93% retention of its initial specific capacitance after 1000 cycles.
