Abstract

A fast switch: A covalent molecular tetrad (see picture), consisting of two electron donor/acceptor pairs acts as a high-speed molecular AND gate when it is sequentially excited using laser pulses having two different wavelengths. This system of using two sequential photodriven electron transfers is analogous to photosystems I and II in green plants which act in series to separate charge for long periods of time.
