The first competitive formation of [4] and [2]supercyclodextrins by self-association of an alpha-cyclodextrin bearing a bisazophenol group
A new Lipophilic alpha-cyclodextrin 1 bearing a bisazophenol group as an internal guest self-associates to form a cyclic dimer 2 and the first [4]supercyclodextrin 3p competitively, and the two successive association equilibria have been first analyzed.
