Fluorescent Composite Hydrogels of Metal–Organic Frameworks and Functionalized Graphene Oxide

GO MOFs! Azobenzoic acid functionalized graphene (A-GO) can act as a structure-directing template that influences hydrogel formation together with metal–organic frameworks (MOFs). Zn2+ MOFs of pyridine derivatives work as framework linkers between the A-GO sheets (MOF–A-GO, see figure). MOF–A-GO exhibits a strong fluorescence enhancement upon gel formation. In addition, MOF–A-GO selectively recognizes trinitrotoluene. Detailed facts of importance to specialist readers are published as "Supporting Information".
