Triplet decay of Mg and Zn phthalocyanins have been studied by laser flash photolysis as a function of concentration. The triplet decay mechanism changes from a near first order in dilute solution to an almost second order in concentrated solutions. This is interpreted in terms of triplet–triplet recombinaison. With the help of a reducing agent, it is shown that the triplet–triplet reaction can lead to charge separation.La décroissance des états excités triplet des phthalocyanines de Mg et de Zn a été étudiée par photolyse éclair laser en fonction de la concentration. Le mécanisme de décroissance du triplet passe d'un premier ordre presque idéal en solution diluée à un quasi second ordre en solution concentrée. Ceci s'explique par une recombinaison triplet–triplet. A l'aide d'un réducteur, la réaction triplet–triplet peut conduire à une séparation de charges.
