Abstract
A three-dimensional Zn(II) framework, [Zn4O(L) 3(DMF)2]·0.5DMF·H2O (1; H 2L = 3,3′-dimethoxybiphenyl-4,4′-dicarboxylic acid) was prepared under a solvothermal reaction in DMF. The structure reveals that the 3-fold interpenetration is stabilized in the framework with a distinct secondary building unit of the formula [Zn4O(R-CO2) 6(DMF)2], slightly different from that of MOF-5. Phase transformations in 1 occur reversibly via two pathways of solvent exchange/resolvation and activation/resolvation, which is indicative of the presence of extensive structural flexibility. Nitrobenzene among tested solvents is selectively detected by 1, and the sensing event was operating repeatedly. The three-dimensional framework of 1 with 3-fold interpenetration is uniquely converted to the two-dimensional Cu phase with no interpenetration, reflecting a drastic dimensionality variation.
