摘要：Zr-based mesoporous metal-organic frameworks (mesoMOFs) with uniform mesochannels and crystallized microporous framework were constructed in a water-based system using amphoteric surfactants as templates. Aqueous-phase synthesis guaranteed the formation of rod-shaped surfactant micelles. Meanwhile, the carboxylate groups of amphoteric surfactants provided the anchoring to bridge Zr-oxo clusters and surfactant assemblies. As a result, the directed crystallization of MOFs proceeded around cylindrical micelles and the hierarchical micro- and mesostructure was produced. The dimensions of mesopores were easily tailored by changing the alkyl chain length of the applied surfactants. The included surfactant was effectively extracted thanks to the exceptional stability of the obtained Zr-based mesoMOFs. The almost complete occupation of the mesopore by cytochromec exemplifies the accessibility of the mesochannels, suggesting the potential applications of the obtained mesoMOFs with bulky molecules.
