Abstract
The formation of inclusion complexes between β-cyclodextrin and diethylenetriamine substituted-pyridine copper(II) perchlorate; [Cu(dien)(sub-py)] (ClO4)2, were studied by spectrophotometric methods. On2T2.2E, the two high peaks were observed as an inclusion complexfor the [β-CD][Cu(dien)(p-Cl-py)]2+ in the ultraviolet region of the spectrum. The β-CD and [Cu(dien)(sub-py)]2+ion formed a 1:1 complex, and the formation constants were decreased with the increasing temperatures, dueto weak binding energy between β-CD and [Cu(dien)(sub-py)]2+ ion. This reaction was controlled by enthalpy.In a correlation of the Hamett substituent constants and formation constants for the reaction, formationconstants were increased by strong binding energy in the inclusion complexes when electron donating groupswere substituted in pyridine ring.
