Rational design and synthesis of covalent organic polymers with hollow structure and excellent antibacterial efficacy†
Abstract
A covalent organic polymer with hollow structure (COP-H) has been synthesized via Sonogashira coupling from the precursors containing positive charge. The formation of COP-H was confirmed by FTIR, solid-state NMR, SEM and TEM. COP-H showed excellent anti-microbial activity because of the cationic charge on the surface of COP-H.
