摘要

Seven upper-rim fully tethered cyclodextrins (URFT-CDs) have been synthesised in a good average coupling yield using the one-st ep "phosphine imide" approach and heir metal complexation behaviour with lanthanides and transition metals was explored. We observed that the A-TE-E light conversion process (antennate effect) occurs in the URFT-CD lanthanide complexes. A molecular redox switch based on the corresponding iron complexes is also reported. A reversible intramolecular translocation of the Fe~(II) and Fe~(III) ions, between two distinct binding cavities has been monitored spectroscopically and achieved by chemical triggering. Finally, a negative allosteric control of iron recognition through the formation of a CD pseudocryptand is discussed.
