Synthesis of tripodands with multiple hydroxyl and amide groups exhibiting fluorescent anion sensing
摘要:
Novel tripodal receptors (T2 and T3) having multiple hydroxyl and amide groups with long alkyl chains (N-dodecylamino and N,N-didodecylamino groups, respectively) were prepared. The broadening of proton signals observed in the 1H NMR spectrum of compounds T2 and T3 in a non-polar solvent (CDCl3) was attributed to intermolecular and/or intramolecular hydrogen bonding. In the fluorescence spectrum, the addition of Bu4NF to the solution of receptors T2 and T3 caused the drastic increase in fluorescence intensity compared with the addition of other anion species.
