摘要：

Two new 2,2':6',2 ''-terpyridine receptors bearing phenol groups, 1 and 2, have been prepared by coupling 4'-(4-aminophenyl)-2,2':6',2 ''-terpyridine with salicylaldehyde or 4-hydroxybenzaldehyde. Both receptors show colorimetric and fluorescent response to F- over other anions in organic solvent. In addition, a strong intramolecular N center dot center dot center dot H-O hydrogen bond was found in 1, which is attributed to its weaker binding ability to F- than that of 2, and an Excited-State Intramolecular Proton Transfer (ESIPT) emission quenching process.
