Abstract

Acetylated cyclodextrins (CDs), including peracetylated α- and β-CDs as well as 2,3-O-diacetylated α- and β-CDs, were found to function as organogelators for organic solvents such as benzene, toluene, and xylenes at ambient temperature. Their organogelation capability was strongly affected by both the CD ring size and the degree of acetylation. Peracetylated α-CD showed the highest organogelation capability among these acetylated CDs, possibly due to the effective construction of three-dimensional networks by the pillar-like assemblies in the organic solvents.
