Abstract

Langmuir-Blodgett monolayers composed of bacterial reaction centers have been investigated by absorption, photoacoustics and time-resolved delayed luminescence in microsecond(s) time range.In reaction centers the excitation energy is able to initiate the charge separation process and then an electron movement across the monolayers takes place with high efficiency. The ability of reaction center to charge separation followed by the electron movement across the membrane could suggest it potential application in a molecular electronic device. Therefore, it is very important to follow the evolution of absorbed energy and its dissipation by radiative and non-radiative processes in such systems. These processes are competitive with the electron transport process.
