Bipyridine-Functionalized Covalent Organic Polymer for Highly Sensitive Turn-On Fluorescent Detection of Zn2+ in Pure Water
A bipyridine-functionalized covalent organic polymer (Bpy-COP) was synthesized as a fluorescent sensor for Zn2+ detection in pure water. Structural characterization confirmed the formation of an imine-linked amorphous polymer incorporating accessible bipyridine coordination sites within a conjugated framework. Upon Z...
