Dinuclear zinc(II) dithiocarbamate macrocycles: Ditopic receptors for a variety of guest molecules

Wong, Wallace W. H.,Curiel, David,Cowley, Andrew R.,Beer, Paul D.

, p. 359 - 364 (2005)

The synthesis of a series of dinuclear zinc(II) dithiocarbamate (dtc) macrocyclic receptors containing aryl spacer groups of different sizes is reported. As evidenced from 1H NMR titration investigations, these receptors have the ability to bin
