However, HCP synthesis typically requires hazardous halogenated solvents e.\u2009g., dichloroethane, dichloromethane and chloroform which are toxic to human health and environment. Herein we hypothesize that the use of halogenated solvents in HCP synthesis can be overcome with deep eutectic solvents (DES) comprising metal halides\u2013FeCl\n                    <jats:sub>3<\/jats:sub>\n                    , ZnCl\n                    <jats:sub>2<\/jats:sub>\n                    that can act as both the solvent hydrogen bond donor and catalyst for polymer crosslinking\n                    <jats:italic>via<\/jats:italic>\n                    Friedel Crafts alkylation.
