Discovery of a single molecule transistor in photosystem II
journal contribution
posted on 2016-04-25, 15:06 authored by Stephen FletcherQuantum theory is used to rationalize the results of
recent high-precision X-ray diffraction studies of photosystem
II. It is proposed that a single molecule transistor regulates the
flow of electrons through this remarkable system. At the core
of the device, electrons flow through an iron(II) d-orbital by a
process of superexchange, at a rate which is gated by the
ambient ligand field. The transistor operates in the negative
feedback mode, and its existence suggests that man-made
molecular logic gates are technologically feasible. We believe
this is the first recorded example of a single molecule electronic
transistor in a living system.
