ConspectusIn this Accounts article, we summarize our recent work on truncating conjugated two-dimensional framework materials down to a single pore, or macrocycle. Conjugated 2D architectures have emerged as one of the most synthetically adaptable motifs for coupling semiconductivity and porosity in metal-organic frameworks (MOFs) covalent organic (COFs). However, despite their prevalence, several limitations. In particular, strong interlayer π-π stacking can limit both processability accessibility internal active sites. We found that simple macrocycles preserve key aspects structure function, including out-of-plane electrical conductivity, while providing improved processability, surface tunability, mass transport properties. first describe synthetic approach general design considerations. Specifically, show how ditopic analogues tritopic ligands commonly synthesis MOFs COFs be used achieve diverse library resemble fragments semiconducting form function. The length peripheral side chains, size aromatic core, solubility intermediates are all variables favoring selective macrocycle formation over undesired linear polymers oligomers. Next, highlight unique advantages provide, atomically precise greater site accessibility. identity chains dramatically impacts colloidal stability well crystal morphology. further solution nanoscale dimensions simplify electronic device fabrication improve electrochemical performance. Finally, end with forward-looking discussion offer bridge between molecules extended frameworks, enabling new application areas fundamental science.
