Abstract

The objective of this work is to elucidate the electrochemical and corresponding optical properties of 8‐hydroxypyrene‐1,3,6‐trisulfonic acid (HPTS), using optically transparent electrodes, thereby deducing its usefulness as a model compound for spectroelectrochemical sensor development. Three pH levels were tested to determine optimal solution conditions for optical signal modulation. The electrolysis of HPTS follows an ECE mechanism, presumably resulting in the formation of a dihydroxy/dione derivative, and modulates the optical response at 405 and 460 nm wavelengths for pH 5 solutions. HPTS is a good candidate for spectroelectrochemical sensor research.

By means of the demodulation technique for the first time the high reduction rate constant of the Sn(I1) ion in sulfuric acid is obtained. From the value of the operational transfer coefficient it follows that a following, potential independent "chemical" step is rate determining. On the addition of
