No full textNew interlocked molecules generated from a podand containing urea units and imidazolium salts using an anion template
No full textA podand containing urea units (L) was found to form interlocked structures with 2,5-dihexylamide imidazolium salts (3路X), 2,5-dihexyl imidazolium salts (4路X), and 2,5-dihexyl benzoimidazolium salts (5路X), where X=Cl-, Br-, and PF6- using anions as templates. The binding ability of L and guest molecules was evaluated by 1H NMR titrations in CDCl3. It was found that L could form complexes with guest molecules in the following order, 3路X>5路X>4路X. Stabilities of the complexes also depended on shape of the templated anions: Cl->Br -鈮玃F6-. Hydrogen bonding and 蟺-蟺 stacking interactions played an important role in the self-assembling of these interlocked molecules. 漏 2003 Elsevier Ltd. All rights reserved
