A study of the metal complexing of naphthalene-2,3-crown ethers using fluorescence spectroscopy: Part III

摘要

2,3-Dioxanaphthalene derivatives of [3n]crown-n macrocycles were synthesised form 2,3-dihydroxynaphthalene and polyglycoldihlides 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-naph-tho[18]crown-6 with LiClO_4,NaClO_4,NaSCN,and KSCN were measured in acetonitrile.Excellent correlaation of spectroscopic,cationic charge-radii and macrocycle backbone size data was found.
