Epoxy-based oligomeric probe bearing naphthalene units for selective turn-OFF fluorescent sensing of fluoride anion

A simple epoxy-based oligomer 1 bearing naphthalene unit at the chain-ends is reported to be highly selective ON–OFF type fluorescent probe for fluoride anion. The titled oligomer displayed fluorescence quenching upon addition of F?, resulting in selective detection of fluoride anion over other anions, such as AcO?, Cl?, Br?, I?, HSO4 ?, NO3 ? and H2PO4 ? in CH3CN. Fluorescence experiments suggest the significant influence of the oligomer chain on the sensitivity and selectivity of 1 towards fluoride anion.

Regioisomer-Specific Mechanochromism of Naphthopyran in Polymeric Materials

Transformation of naphthopyran into a colored merocyanine species in polymeric materials is achieved using mechanical force. We demonstrate that the mechanochemical reactivity of naphthopyran is critically dependent on the regiochemistry, with only one pa

Syntheses and Structures of Synthetic Carboxylic Ionophores Containing 2,3-Naphthylene Groups

Two derivatives of ω-hydroxy carboxylic ionophore 2-ethoxy>phenoxy>ethoxy>phenoxy>ethoxy>phenoxy>methyl>benzoic acid 1, 2-ethoxy>phenoxy>ethoxy>phenoxy>ethoxy>-2-naphthyloxy>methyl>benzoic acid 2 and 2-ethoxy>-2-naphthyloxy>ethoxy>phenoxy>ethoxy>-2-naphthyloxy>methyl>benzoic acid 3, were prepared.Both compounds exhibited high K+ selectivity over Na+, as did 1.The structures of the Rb salt of 2 and the K salt of 3 were determined by single-crystal X-ray analyses.Both ionophores formed pseudocycles by a head-to-tail hydrogen bond between the hydroxy and carboxylato groups and enclosed each cation like the seam of a tennis ball to make lipophilic complexes.However, the three-dimensional structures of the two hydrophobic salts differed from each other in spite of the similarity of the primary structures, which might be due to the interaction of the aromatic rings.
