— When chlorophyll is adsorbed to polyethylene‐tetradecane particles along with ligating amphiphiles, and pheophytin is present also, a slow but irreversible photobleaching of the chlorophyll is observed in suspensions of the particles in aqueous media. It is suggested that the reaction starts by transfer of an electron from singlet excited chlorophyll to pheophytin and concludes by hydration and reduction of the chlorophyll radical cation.
