Abstract:
The present invention is related to a class of stable 2D covalent organic frameworks with multiple dimethyl amino groups that can trap carbon dioxide at ambient temperature and pressure, and an economical, environmentally-friendly process for the generation of transient surface charges and subsequent self-exfoliation of the COF into ultrathin nanosheets. The said exfoliated material possess activity against pathogenic bacteria. The invention further discloses a carbon dioxide induced exfoliation process that is completely reversible upon heat treatment, whereby control over bacterial growth is achieved via an efficient antibiotic switch.
