Microporous sensor: gas sorption, guest exchange and guest-dependant luminescence of metal–organic framework

Zn(II)-containing metal–organic framework (MOF) [Zn4(dmf)(ur)2(ndc)4] (ndc2− = 2,6-naphtalenedicarboxylate, ur = urotropin, dmf = N,N′-dimethylformamide) was synthesized and characterized by X-ray crystallography and gas sorption analysis. Host MOF retains its crystallinity after guest removal and exchange. Single-crystal to single-crystal formation of different host–guest systems with benzene and ferrocene was investigated. Interesting guest-depended luminescence properties of the porous host framework were observed.
