In some situations, an electrochemical detection at porous
electrodes can be advantageously combined with a spectroscopic
detection [6– 9]. In general, spectroelectrochemistry allows to
analyze single and multiple electron-transfer processes and redox
reactions [10] and authorizes a multimode selectivity beneficial forthe analytical chemistry [11,12] . A transparent material is however
needed to perform spectroelectrochemical measurements through
the electrode surface [12] .
