CHEMILUMINESCENCE INITIATED BY COMPLEX-FORMATION IN SOLUTIONS OF 1,2-DIOXETANE AND LANTHANIDE PERCHLORATES

The spectral and activation parameters of chemiluminescence in the the rmal decay of 1,2-dioxetane based on adamantylideneadamantane in aceto nitrile in the presence of Tb-III, Eu-III, Pr-III, Ce-III, and Gd-III perchlorates and UO2(NO3)(2) have been studied. Two types of catalysis by metals, luminescent and nonluminescent, can be distinguished in th e framework of one mechanism of dioxetane decay initiated by metal-per oxide complex formation. The mode of catalysis depends both on the pre sence of suitable energy levels in the metal ion to which the intracom plex transfer of excitation from the 3n,pi-state of the ketone that a ppears in the decay of dioxetane in a catalytic complex can occur and on the ratio of the quantum yields of luminescence of the ketone and t he metal ion that is the catalytic activator of luminescence.
