A new surfactant-introduction strategy for separating the pure single-phase of metal–organic frameworks†
Abstract
By introducing different surfactants into a reaction system, two previous mixed-phase Ni(II)–MOFs constructed from an undeveloped pyridyl-tetracarboxylate and Ni(II) salts were successfully isolated to obtain two pure products. Compound 1 exhibits a 3D H-bonded network with (3,8)-connected {4.52}2{42.56.614.72.84} topology, while 2 features a 3D 2-fold interpenetrating framework with a self-penetrating (3,4,4)-connected {62.103.12}{63}2{64.8.10}2 topological net.
