The charge-transfer complexation reaction between iodine and dibenzopridino-18-crown-6 (DBPY18C6) has been investigated spectrophotomertically in chloroform solution at different temperatures. The resulting comlex was formulated as (DBPY18C6...I(+))I(-/3).The enthalpy and entropy of the complex formation were evaluated from the temperature dependence of the formation constant. The resulting charge-transfer complex is both enthalpy and entropy stabilized. The rate constants at various temperatures and the activation parameters were evaluated.
