Abstract

We examined the alkali metal-recognition property and the structure of an amphiphilic crown ether azoprobes (15C5-Azo-Cn ; n = 4, 6, 8)/cyclodextrin (CyD) complex in water by UV-Vis absorption spectroscopy and circular dichroism (CD) spectroscopy. The 15C5-Azo-Cn formed a stable complex with γ-CyD by making H-aggregate, and its apparent affinity was intensified by about 10 times for K+, and not for Na+. It was suggested that a H-aggregate of 15C5-Azo-C4 and 15C5-Azo-C6 bound one γ-CyD molecule, and 15C5-Azo-C8 bound one or two γ-CyD molecules by the addition of K+. The induced CD analysis revealed that γ-CyD bound with both the phenylazo moiety and the alkyl chain unit of the azoprobe by the addition of K+, although γ-CyD bound with mainly the phenylazo moiety of azoprobe by the addition of Na+.
