Complexation by α- and β-cyclodextrin C(6) linked homo- and hetero-dimers of Brilliant Yellow tetraanion: a study of host-guest size relationships

Abstract

Complexation by α- and β-cyclodextrin (αCD and βCD) homo- and heterodimers linked at C(6) by a urea linker (N,N′-bis(6A-deoxy-α-cyclodextrin-6A-yl) urea, N-(6A-deoxy-α-cyclodextrin-6A-yl)-N′- (6A-deoxy-β-cyclodextrin-6A-yl)urea and N,N′-bis(6
