Unusual photoelectrochemical properties of titanium dioxide modified with iron(II) complexes allow application of these materials for the construction of various optoelectronic devices including switches, logic gates and even demultiplexers. All these devices use optical input and electric output. The mechanism of the photoelectrochemical photocurrent switching (PEPS) effect is described in detail on the basis of experimental data and quantum-chemical calculations. All the collected data indicate the importance of the complex–semiconductor binding mode.
