Interactions of select boric acid derivatives with β-cyclodextrin were investigated. All products were obtained employing the grinding-induced mechanochemical approach. It was found that phenylboronic acid, benzoxaborole and boric acid form non-covalent, hydrogen bonding-based systems with β-cyclodextrin, whereas catechol and pinacol esters of phenylboronic acid as well as ferroceneboronic acid form host-guest inclusion complexes. The interactions were probed using spectroscopic methods: 1 H NMR, 1 H-1 H ROESY NMR, 1 H DOSY NMR, FT-IR. Association constant values were evaluated by 1 H DOSY NMR. The highest association constant was found for boric acid (117.5 ± 2.5 M−1 ), whilst the lowest for benzoxaborole (14.8 ± 0.3 M−1 ). The study shows the influence of boron compound structure on the nature of the assembly formed with β-cyclodextrin, laying up the basis for future work with such supramolecular systems.
