Abstract
Upon immersing into water, the chlorophyll a(chl a)/poly vinyl acetate) film cast from dioxane or dimethyl sulfoxide (DMSO) showed a transformation from chl a-dioxane aggregate (692 nm) to monomeric(668 nm) or from chl a-DMSO aggregate (695 nm) to (chl a·2H2O)n(746 nm), respectively. The platinum electrodes coated By the two types of transformed films showed the opposite direction of photo-induced potential shift.Keywords
