Interpretive Summary: Metal-organic framework (MOF) films are porous films that possess unique chemical properties that are highly desirable for energy, bio-medical and agricultural applications for gas storage and release. However, synthesizing MOFs as freestanding films or sheets that retain morphological and structural integrity has been technically challenging. In this study, we developed a new method to synthesize MOFs with desired morphologies. This method is easy to use, and low cost. The availability of this method could expand the potentials of MOF films for broad applications in the future, including the potential to store and release of both inert and bioactive gases (e.g., ethylene) for a broad range of applications.

Technical Abstract: Metal-organic framework (MOF) films and nanosheets are highly desirable for commercial applications, especially in molecular sieving and catalytic membranes. However, synthesizing MOFs as freestanding nanosheets that retain morphological and structural integrity has been technically challenging. In this study, a facile and template-free solvothermal method was developed to synthesize cupric terephthalate MOFs with controlled morphologies. The use of different copper (II)-ligand coordination complexes mediates the controlled MOF crystal growth and morphology, including free-standing agglomerated nanosheets. This work provides a bottom-up approach to synthesize mesoporous/macroporous MOF nanosheets in a simple and scalable way, which could expand the potentials of MOF nanosheets for energy and biomedical applications in the future.
