Abstract

Incorporation of nitrogen functionality onto the high surface area porous polymeric network are very demanding in designing suitable heterogeneous organocatalyst having surface basicity. Here we report the synthesis of a new N‐rich triazine based microporous organic polymer (TrzMOP) through a simple and efficient condensation pathway involving the reaction between 1,4‐bis(4,6‐diamino‐s‐triazin‐2‐yl)‐benzene (SL‐1) and 2,5‐thiophene dicarboxaldehyde. The material has been characterized by using powder XRD, FTIR spectroscopy, solid state magic‐angle spinning 13C NMR, CHN analysis, FESEM, HRTEM, CO2‐TPD and N2 adsorption/desorption techniques. This nitrogen‐rich new porous organic polymer showed very high catalytic efficiency for one‐pot proficient synthesis of polyhydroquinoline derivatives via microwave assisted condensation reaction. As little as 8 mg of catalyst was found to be effective under the optimum reaction conditions. In addition, TrzMOP catalyzed synthesis of biologically active polyhydroquinoline derivatives are very cost effective, scalable, less time consuming, and environmentally benign compared to those of currently used as heterogeneous catalysts.
