Abstract

A composition of matter for selective binding of at least one heavy metal comprising at least one porous metal-organic framework (MOF) with unsaturated coordination sites, at least one organic ligand functionalized with at least one functional group tailored to bind to the at least one MOF, and at least one separate functional group tailored to bind to the at least one heavy metal.
