Electron-transfer kinetics of copper(II/I) macrocyclic tetrathiaether complexes. Influence of ring size upon gated behavior

The values of the electron self-exchange rate constants, k 11(ex) , for the copper(II/I) complexes formed with the cyclic tetrathiaethers [13]aneS 4 and [15]aneS 4 have been determined using 1 H-NMR line-broadening measurements in D 2 O at several different temperatures
