Outline of Final Research Achievements

This project aims at the construction of chemically stable covalent organic frameworks (COFs) by photo-dimerization of acenes. During this grant period, mainly examined was the synthesis of macrocyclic compounds that can serve as COF monomers. Systematic investigation has led to successful formation of macrocycles through one-step connection of three each of o-phenylenediamine and boronic acid units (six molecular units in total). The diazaborole motif, which is formed by the dehydration condensation between o-phenylenediamine and boronic acid, can be formed under thermodynamic control and relatively stable to hydrolysis, being ideal for the purpose of this project. The present work paves the way toward the synthesis of COFs through photodimerization of acenes. In addition, the reaction conditions optimized for the macrocycle synthesis might be directly applied to the synthesis of a new class of COFs assembled via the diazaborole linkage.
