Synthesis of redox active large macrocyclic hosts and the recognition of secondary ammonium salts
摘要:
Interconvertible macrocyclic hosts containing thiol groups or a disulfide linkage in the binding cavity have been synthesized. The binding affinities of the reduced and oxidized forms toward benzylammoium derivatives are completely reverse. Formation of pseudorotaxane is suggested upon the host-guest complexation.

Control of binding affinity to paraquat by novel macrocyclic systems responding to redox reactions
摘要:
Interconvertible crown ethers bearing two thiol groups or a disulfide moiety by redox reactions have been prepared. The binding affinity to paraquat is Controlled by using these redox active molecular systems. Efficient contribution of charge transfer interaction between the thiol hosts and the guest was suggested by UV-vis spectroscopy. (C) 2002 Elsevier Science Ltd. All rights reserved.
