- 中文摘要: The complex formation reactions between iodine and DBzDA18C6, A15C5 and N-phenylA15C5 have been studied spectrophotometrically in chloroform solution. In the case of DBzDA18C6 is the resulting 1:2 (ligand?I+)I3-, while, in the case of A15C5 and N-phenylA15C5 a 2:2 molecular complex of [(ligand)2?I+]I3- type was formed. The spectrophotometric results indicate that gradual release of triiodide ion from its contact ion paired form in the molecular complex into the solution is the rate-determining step of the reaction. The kinetic rate constants for the complexation reactions were determined at different temperatures, and activation parameters were calculated from Arrhenius and Eyring equations.
