摘要: The design and function of novel supramolecular fluoroionophore/cyclodextrin (CyD) complex sensors for ion molecule recognition in water are reviewed. For the crown ether fluoroionophore/c-CyD complex, dimerization fluoroionophore inside c-CyD is found to be selectively promoted by alkali metal binding, thereby resulting metal-ion-selective pyrene dimer emission water. This successfully utilized a podand sensing toxic lead boronic acid fluoroionophore/b-CyD binds sugars produces increased fluorescence response mechanism appears due suppression photoinduced electron transfer (PET) from donor trigonal phenylboronic acceptor. provided
