Abstract

An electrochemical sensor incorporates a ferrocenophane which is a compound with at least one bridging group covalently attached to and connecting the two cyclopentadiene rings associated with the same iron atom. This bridging group maybe tetramethylene. As compared to an equivalent sensor with ferrocene, the tolerance of elevated temperature is improved and so is the working life at ambient temperature.
