Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The N₄ ligand 1‐{6‐[1, 1‐bis(pyridin‐2‐yl)ethyl]pyridin‐2‐yl}‐<italic>N</italic>, <italic>N</italic>‐dimethylmethanamine (L) is presented. It has been used to obtain the copper(I) complex [CuL(MeCN)]PF₆ and the iron(II) complex [Fe(CN)₂L]. Aerobic oxidation of the copper(I) complex is unspecific at room temperature. Anaerobic oxidation in solution, which is very sluggish, occurs with formation of the copper(II) complex [Cu^IIFL]PF₆, suggesting concomitant hydrolysis of hexafluorophosphate initiated by traces of water. The iron(II) complex adsorbed at a TiO₂ surface is an efficient photosensitiser of the support. Photoelectrochemical photocurrent switching (PEPS), which can be initiated by changing the electrochemical potential and photon energy, is very pronounced. The construction of a simple photoelectrochemical NOR logic gate has been demonstrated.</p> </abstract>
