摘要: The protonation constants of cyclen– and cyclam–pyridine [1-(pyridin-2-ylmethyl)-1,4,7,10-tetraazacyclododecane (L1) 1-(pyridin-2-ylmethyl)-1,4,8,11-tetraazacyclotetradecane (L2), respectively] the stability (log β110) corresponding copper complexes ([CuL1]2+ [CuL2]2+) were determined by potentiometric titrations. subsequently isolated characterised X-ray diffraction, UV/Vis spectroscopy electrochemical studies. [CuL2]2+ complex adopts two distinct stable geometries (trans I III), which mainly differ macrocycle configuration. trans III configurational isomer can be converted into one electron transfer.
