Abstract

Reaction of eight 9-benzylidene-N-methylacridan derivatives with singlet oxygen results in chemiluminescence quantum yields giving a good fit if plotted versusHammett's “σ” values. To account for the deviation of two derivatives, the quenching constants of the leaving moieties on the fluorescence of the primary emitter are compared with the diffusion constant in the medium, verifying an earlier suggestion that even small quenching efficiencies of the leaving moiety greatly affect chemiluminescence quantum yields.

Zusammenfassung

Die Reaktion von acht 9-Benzyliden-N-methylacridanen mit Singlet-Sauerstoff ergibt Chemilumineszenz-Quantenausbeuten, die eine gute lineare Abhängigkeit gegenüber denHammett'schen σ-Werten zeigen. Um die Abweichung zweier Derivate zu erklären, wurden die Quench-Konstanten für die bei der Fluoreszenz des Primär-Emitters entstehenden Moleküle in Relation zur Diffusionskonstante gesetzt. Es bestätigte sich die frühere Vermutung, daß auch eine geringer Quench-Effizienz von entstehenden Produkten einen sehr großen Effekt auf die Chemilumineszenz-Quantenausbeuten haben kann.
