  • Title: Switching between supramolecular dimer and nonthreaded supramolecular self-assembly of stilbene amide-alpha-cyclodextrin by photoirradiation.
    Author: Yamauchi K, Takashima Y, Hashidzume A, Yamaguchi H, Harada A.
    Journal: J Am Chem Soc; 2008 Apr 16; 130(15):5024-5. PubMed ID: 18335989.
    Abstract:
    3-trans-Stilbene amide-alpha-cyclodextrin (3-trans-Sti-alpha-CD) formed a double-threaded dimer in aqueous solutions. In contrast, the photoisomerization of the stilbene moiety in 3-Sti-alpha-CD from trans to cis leads to the structural changes from the double-threaded dimer to nonthreaded supramolecular assemblies in aqueous solutions. The structures of these supramolecular complexes have been found to be controllable by photoirradiation.
