A triazine-cored covalent organic polymer (COP) was designed and synthesized via amine linkages under ambient conditions. The novel architecture of the COP was fully characterized via spectroscopic and analytical techniques. The present COP demonstrates a quick, portable and reversible chromogenic response towards noxious HCl vapours.
A new micro-spherical covalent organic polymer was synthesized, which exhibits reversible chromogenic response towards the sensitive detection of the noxious HCl gas.
