| Abstract |
Fluorescent ion pair receptors were designed and synthesized for selective recognition of LiCl. They consist of tripodal pyridine units for cation recognition and urea groups linked to the pyridine groups as anion binding motifs. The pyrene was also introduced into the receptors as a fluorescent signaling unit. 1H NMR and fluorescence spectroscopic analysis revealed that the receptors possessed an ability to bind LiCl with high selectivity over other chloride salts. Upon exposure of the receptor to LiCl, significant fluorescence enhancement was observed as a result of LiCl binding with the receptors inhibiting PET (photo-induced electron transfer). |
