Facile synthesis and grafting of N2O2-Cu(II) Schiff base complex onto graphene oxide surface: Aspects of its antimicrobial, anticancer, antiCOVID-19 and photodegradation of methylene blue

In this study, a facile synthesis and grafting method is reported for tetradentate Cu(II) Schiff base complex onto the surface of graphene oxide (GO). The Schiff base Cu-complex was synthesized through the condensation reaction between 2,3-diamino pyridine and 2-hydroxy-1-naphthaldehyde, followed by the addition of Cu(II) ion to afford N2O2-Cu(II) complex.
