Three zinc metal-organic frameworks (MOFs), {ZnL(chd)} (1), {[Zn(L)(oba)]·DMF·HO} (2) and {[Zn(L)(sdb)]·HO} (3) [L = E,E-2,5-dihexyloxy-1,4-bis-(2-pyridin-vinyl)-benzene; Hchd = 1,4-cyclohexanedicarboxylic acid, Hoba = 4,4'-oxybisbenzoic acid, Hsdb = 4,4'-sulfonyldibenzoic acid], have been hydrothermally synthesized. We explored their applications in detecting ions, and the result shows that they all show highly selective sensing for Fe and CrO ions.
