Two-dimensional (2D) covalent organic frameworks (COFs) are promising polymeric crystalline nanomaterials with broad applications. In order to realize the true potential of these thin film materials, precise control of thickness and morphology is necessary and advanced synthetic techniques including various forms of interfacial synthesis have been widely explored. In this talk, we will highlight some of our recent efforts in the synthesis and engineering of thin film COFs. Corresponding nanomechanical characterizations of 2D COFs will be reported.Additionally, heterogeneous integration of these thin films with other inorganic and organic materials will be discussed for applications in photocatalyst and energy storage applications, revealing exciting opportunities to integrate COF thin films with other state-of-the-art material and device systems.
