Phthalocyanine derivatives have perhaps received more attention than any other class of dyes as sensitizers for photodynamic therapy and most favoured are the aluminium and zinc derivatives. Photoinduced electron transfer in donor-acceptor molecules has been extensively studied, in particular for covalently linked dyads in solution as model systems of natural photosynthesis to harvest efficiently solar energy. In this study, the characterizations for immobilization o f R. sphaeroides on two phthalocyanines were evaluated. There are two solvent for phthalocyanines, water and SDS. In order to determine electron reaction of cell bound phthalocyanines, we are confirmed cyclic voltammetry measurement. R. sphaeroides bound ZnPc in water solvent and CuPc in SDS solvent were shown active electron reactions. It was correlated with the amount of cell bound phthalocyanine by photo-luminescence at 683nm for emission and at 600nm for excitation. In addition, electron reactions of R. sphaeroides on phthalocyanines were increased for 10 days storage period. Phthalocyanines as electron donoron on R. sphaeroids can apply for improving photosynthetic efficiency.
