Controlled Axial Growth and Morphological Evolution of Three-Dimensional Covalent Organic Frameworks Unveiled by Single-Crystal X-ray Diffraction.
Precisely tailoring the macroscopic morphology of covalent organic frameworks (COFs) fundamentally drives their physicochemical properties. However, the robust and highly directional nature of covalent bonds makes such control at the single-crystal level a formidable challenge. Resolving this bottleneck, we establish a...
