Witryna7 kwi 2024 · Naphthotubes with hydrogen-bond acceptors (ether, ester, and imine) prefer to bind org. cations; naphthotubes with hydrogen-bond donors (urea, thiourea, and amide) can bind neutral mols.; amine naphthotubes are stimuli-responsive to acid/base. In particular, the water-sol. amide naphthotubes are able to selectively … Witryna1 paź 2024 · In this study, we investigated the volumetric properties for the binding of 1,4-dioxane to a pair of naphthotubes (i.e., anti- and syn-isomers), each possessing two inwardly directed amide groups in the hydrophobic cavity, using nuclear magnetic resonance and fluorescence spectroscopy coupled with pressure perturbation.
