Abstract [eng] Electrochemical and spectroelectrochemical properties of molecular glass 3,4-ethylenedioxythiophene-2-carbaldehyde N,N-diphenylhydrazone are reported. 3,4-ethylenedioxythiophene-2-carbaldehyde N,N-diphenylhydrazone showed glass transition at 37 °C and relatively high thermal stability with the initial decomposition temperature at 219 °C. The amorphous film of the compound showed cathodic and anodic responses with a homogeneous change of color from yellow to blue-green in the anodic region. At 4 V two new absorption bands arise in the absorption spectrum of the compound studied, which are absent at 0 V. One is near 670 nm and the second is at 770 nm. Addition of polymethylmethacrylate and poly(N-vinylcaprolactam) enhances electrochromic properties of the material.
