Three different metal–organic frameworks derived from a one-pot crystallization and their controllable synthesis

Abstract

Three different Co-MOFs, [Co₃(L)₂(DPDP)]_n (1), [Co(HL)(DPDP)]_n (2) and {[Co(HL)(1/2DPDP)₃(H₂O)]·H₂O}_n (3) (H₃L = 4,4′,4′′-(nitrilotris(methylene))tribenzoic acid, DPDP = 4,4′-(2,5-dibutoxy-1,4-phenylene)dipyridine) have been co-crystallized in a one-pot reaction. Based on the significant differences between the three structures, we adopt solvents to ultimately regulate acquisition of pure crystals of the three compounds.
