Abstract
Abstract 2,3-Dioxanaphthalene derivatives of [3 n ]crown- n macrocycles were synthesised from 2,3-dihydroxynaphthalene and polyglycoldihalides and studied for their cationic recognition properties using steady state fluorescence spectroscopy. The association constants for the interaction of 2,3-naphtho[12]crown-4, 2,3-naphtho[15]crown-5 and 2,3-naphtho[18]crown-6 with LiClO 4 , NaClO 4 , NaSCN, and KSCN were measured in acetonitrile. Excellent correlation of spectroscopic, cationic charge-radii and macrocycle backbone size data was found.
