A thermodynamic and kinetic interpretation of the macrocyclic effect. Polarographic studies on copper(II) 1,4,7,10-tetraazacyclododecane complexation
Abstract
Polarographic studies on CuII-1,4,7,10-tetra-azacyclododecane (cyclen) complexation have shown that the thermodynamic and kinetic macrocyclic effect is evident despite the unfavourable steric constraints, and that the increased stability constant of CuII-cyclen compared to CuII-trien is accounted for solely by the entropy term.
