Calix[4]arene-(1,2-phenylene-crown-6,crown-6) as an extraordinarily effective macrocyclic receptor for the univalent silver cation
Original language description
On the basis of extraction experiments and gamma-activity measurements, the extraction constant corresponding to the equilibrium Ag+(aq) + 1 center dot Cs+ (nb)reversible arrow 1 center dot Ag+(nb) + Cs+ (aq) occurring in the two-phase water-nitrobenzene system (1 = calix[4]arene-(1,2-phenylene-crown-6, crown-6); aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log K-ex (Ag+, 1 center dot Cs+)= -1.3 +/- 0.1. Further, the very high stability constant of the 1 center dot Ag+ complex in nitrobenzene saturated with water was calculated for a temperature of 25 degrees C: log beta(nb) (1 center dot Ag+) = 9.3 +/- 0.2. Finally, by using quantum mechanical DFT calculations, the most probable structures A and B of this cationic complex species, which are obviously in a dynamic equilibrium, were derived.
