We have synthesized a schiff base receptor, N,N'-ethylene-bis(salicylidenea
minato) that exhibits the strong binding ability to salicylaldehyde as a gu
est. The binding characteristics of the interaction between the schiff base
and salicylaldehyde have been monitored by H-1 NMR spectroscopy. The rever
sible binding mechanism depending upon the solution pH has been monitored b
y 1H NMR spectroscopy during the acid titration reaction. (C) 2001 Elsevier
