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 improvements of electron reactions from immobilization of 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 phthalocyanines. In addition, it was found that the indirect immobilization of R. sphaeroides on phthalocyanines was confirmed when it was supplemented by sodium bicarbonate. Phthalocyanines as electron donor on R. sphaeroids can apply for improving photosynthetic efficiency.
