Small cavitands specifically binding a water molecule.
[structure: see text] Three new C(2v) cavitands based on resorcin[4]arene bind water specifically at low temperature in CD(2)Cl(2) or CDCl(3) due to their complementarity to water as well as the solvophobic interaction. The averaged DeltaH(o) and DeltaS(o) values are -2.3 kcal mol(-1) and -128 cal mol(-1) K(-1), which gave the averaged -DeltaG(o) of 1.9 kcal mol(-1) at -50 degrees C in water saturated CD(2)Cl(2).
