Nanomechanics signifies a key tool to interpret the macroscopic mech. properties of a porous solid in the context of mol.-level structure. However, establishing such a correlation has proved to be significantly challenging in porous covalent organic frameworks (COFs). Structural defects or packing faults within the porous matrix, poor understanding of the crystalline assembly, and surface roughness are critical factors that contribute to this difficulty. In this regard, we have fabricated two distinct types of COF thin films by controlling the internal order and self-assembly of the same building blocks. Interestingly, the defect d. and the nature of supramol. interactions played a significant role in determining the corresponding thin films’ stress-strain behavior. Thin films assembled from nanofibers (~1-2μm) underwent large deformation on the application of small external stress (Tp-Azofiber film: E ≈ 1.46 GPa; H ≈ 23 MPa) due to weak internal forces. On the other hand, thin films threaded with nanospheres (~600 nm) exhibit a much stiffer and harder mech. response (Tp-Azosphere film: E ≈ 15.3 GPa; H ≈ 66 MPa) due to strong covalent interactions and higher crystallinity. These porous COF films further exhibited a significant elastic recovery (~80%), ideal for applications dealing with shock-resistant materials. This work provides in-depth insight into the fabrication of industrially relevant crystalline porous thin films and membranes by addressing the previously unanswered questions about the mech. constraints in COFs. In the part of experimental materials, we found many familiar compounds, such as 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Product Details of 34374-88-4)
