摘要：

The tweezer-type receptors 3, 8. and 11 are synthesized and are used for the binding of nitrate anions. Hereby, an additive effect of the hydrogen bonds on the free enthalpy of complexation is observed. Every additional hydrogen bond increases DeltaG(HG), for the binding of nitrate in D-chloroform. by approximately 2-3 kJ (.) mol(-1). (C) 2001 Elsevier Science B.V. All rights reserved.
