Selective Redox-Active Molecular Receptors for K+ and Ag+
摘要:
Two new tetrathiafulvalene based receptors in which the favorable redox properties of the tetrathiafulvalene unit are coupled to either a benzo-crown (X = O) or a dithlabenzo-crown (X = S) ether binding site were designed and synthesized as receptors for K+ and Ag+. The receptors display a good (K+, X = O) to strong (Ag+, X = S) affinity toward the cation and a high discrimination against other metal cations.
