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). Zn 2+ 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.
