Abstract

Two novel applications of electrochemical techniques are discussed based on the photochemical/elctrochemical hybridized reaction of azobenzene species. The first is photoelectrochemical information storage. This new recording technique has advantages of ultrahigh storage density (up to 1012 bits cm−2), non-destructive optical readout and rewritability. The second is electrochemical actinometry, in which the trans—cis photoisomerization of 4-octyl-4′-(5-carboxy-pentamethylene-oxy)-azobenzene (ABD) in an assembled monolayer film is used to detect incident light, and the quantification of the cis-ABD thus produced is performed through its selective electrochemical reduction, leading to an instantaneous evaluation of the irradiation intensity.
