Jc. Rodriguezubis et al., A SIMPLE POLYHETEROTOPIC MOLECULAR RECEPTOR DERIVED FROM BISPYRAZOLYLMETHANE SHOWING NEGATIVE ALLOSTERIC COOPERATION OF ZN(II), Tetrahedron letters, 35(8), 1994, pp. 1295-1298
The preparation of 1 as a model for negative allostery is described. T
ransport experiments (bulk liquid membrane) of alkyl di- and monoammon
ium cations in the presence or absence of ZnI2 in the receiving phase
evidenced strong negative allosteric effects of the metal towards ammo
nium complexation.
