We report the activation energy determination corresponding to the recombination of the radical cation electron moiety created through photoionization of the 1,6-diphenyl-1,3,5-hexatriene molecule incorporated in ZSM-5 zeolite channels. We demonstrate that the charge separated state stabilization in zeolite does not depend only on the Al content but also on the Al repartition.
