Novel (1,2-3,5)-calix[5]arene-bis-crown-3 and (1,3)-calix[5]arene-crown-3 derivatives, bearing one or three ureido moieties at the lower rim, respectively, have been synthesized and investigated as heteroditopic receptors for inorganic and organic salts. Tris-ureido-calix[5]arene-crown-3 10, in particular, efficiently binds 2-phenylethylamine hydrochloride (PEA center dot HCl) as a spatially separated ion pair.

Abstract
Novel (1,2-3,5)-calix[5]arene-bis-crown-3 and (1,3)-calix[5]arene-crown-3 derivatives, bearing one or three ureido moieties at the lower rim, respectively, have been synthesized and investigated as heteroditopic receptors for inorganic and organic salts. Tris-ureido-calix[5]arene-crown-3 10, in particular, efficiently binds 2-phenylethylamine hydrochloride (PEA center dot HCl) as a spatially separated ion pair.File in questo prodotto:
