ABSTRACT=<p>We report channel confinement properties of an electron-deficient boron host derived from the orthogonal B←N interaction between a boronic ester and <italic>trans</italic>-pentafluorostilbazole. The boron host forms one-dimensional channels in the crystalline solid state when crystallized with common electron-rich aromatic petrochemicals (i.e., benzene, toluene, <italic>o</italic>-xylene) to form solvates and a cocrystal with stilbene. Molecular confinement of the electron-rich molecules in the solids is achieved through a combination of aryl–perfluoroaryl interactions (π-π<sub>F</sub>) and hydrogen bonds.</p>
