New Fluorescent Photoinduced Electron Transfer Chemosensor for the Recognition of H2PO4

New Fluorescent Photoinduced Electron Transfer Chemosensor for the Recognition of H2PO4

The fluorescent chemosensor 1 bearing two imidazolium groups at the 1,8-position of anthracene has been designed for the recognition of anions through the (C−H)+- - -X- hydrogen bond formation. As unique tweezer-like binding of 1 with anions is predicted by the ab initio calculations, strong anion-b...

Zusammenfassung:The fluorescent chemosensor 1 bearing two imidazolium groups at the 1,8-position of anthracene has been designed for the recognition of anions through the (C−H)+- - -X- hydrogen bond formation. As unique tweezer-like binding of 1 with anions is predicted by the ab initio calculations, strong anion-binding properties of chemosensor 1 are demonstrated by using fluorescence as well as 1H NMR.
