Absorbance changes of solutions of iodine and 15-crown-5, 18-crown-6 and dibenzo-18-crown-6 in chloroform were studied. Absorption maxima due to the triiodide anion were observed. The obtained rate constants and their temperature dependence indicate formation of molecular complexes (cyclic polyether...I2) and (cyclic polyether...I(+)) I(-).
