The kinetics of complex formation between Cu(II) and L1, L2, and L3 were investigated in acidic aqueous solutions using the stopped-flow method. The stability constants of the complexes were determined by spectrophotometric titration (T = 293 K, = 0.1 mol L-1 NaClO4), using a diode array UV-Vis spectrophotometer equipped with peristaltic pump and pH meter. The stability constants for the complexes were CuL1 CuL2 CuL3. Activation enthalpies (H#) of these complexes were 55 kJ mol-1 for CuL1, 61 kJ mol-1 for CuL2, and 36 kJ mol-1 for CuL3, respectively.eninfo:eu-repo/semantics/closedAccessComplexationPolyamineKineticsStability constantsStopped-flowSpectrophotometric titrationArticle63244299430810.1080/00958972.2010.535144Q2WOS:0002851494000122-s2.0-78650205919Q3
