Design and synthesis of a multifunctional porous N-rich polymer containing s-triazine and Tröger's base for CO2 adsorption, catalysis and sensing

A multifunctional porous N-rich polymer containing s-triazine and Tröger's base was synthesized. It shows selective adsorption for CO₂, colorimetric performance for HCl and good catalytic activity in the Knoevenagel condensation.
