Abstract :
We prepared anion receptors based on acyclic phenol-formaldehyde oligomer bearing thiourea groups. The dimer (1b) and trimer (1c) showed the binding selectivity toward chloride (Cl-) and hydrogensulfate (HSO4-), respectively. This selectivity will be attributed to the fit size and shape of anionic species,which favor formation of a stable host-guest complex through the multiple intermolecular hydrogen bonding.
