Herein we report that 4-pyridinylboronic acid (1) in the solid state self-assembles into tetrameric macrocyclesvia B−N bond formation. The tetramers are linked via O−H···O bonds resulting in a material that can be exfoliated via sonication to give thinner sheets as we demonstrate via Fourier transform infrared spectroscopy, transmission electron microscopy, selected area electron diffraction, and atomic force microscopy experiments. For comparison, the structure of the related compound 4-(pyridin-4-yl) phenylboronic acid (2) is also discussed.

Abstract
Herein we report that 4-pyridinylboronic acid (1) in the solid state self-assembles into tetrameric macrocyclesvia B−N bond formation. The tetramers are linked via O−H···O bonds resulting in a material that can be exfoliated via sonication to give thinner sheets as we demonstrate via Fourier transform infrared spectroscopy, transmission electron microscopy, selected area electron diffraction, and atomic force microscopy experiments. For comparison, the structure of the related compound 4-(pyridin-4-yl) phenylboronic acid (2) is also discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
