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

Zn(II)-containing metal-organic framework (MOF) [Zn(4)(dmf)(ur)(2)(ndc)(4)] (ndc(2-) = 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.
