Logical progression: Optoelectronic XOR and INH logic gates based on two light inputs and an electrical output were demonstrated using a nanocrystalline TiO2 dye-sensitized solar cell. The Grätzel-type cell was generated using a ruthenium complex as dye, with reverse injection of electrons at the semiconductor/dye interface (see picture).

    ABSTRACT: A new bioinspired nanomaterial has been obtained by chemisorption of folic acid onto nanocrystalline titanium dioxide. The organic chromophore is linked with the semiconductor surface via the glutamate chain and anchored with the carboxylate group. The geometry and electronic structure of the chromophore was studied in detail with DFT. Photoelectrochemical studies revealed photosensitization of the new material towards visible light. The photoelectrodes composed of the folic acid/titanium dioxide hybrid material generated photocurrent over a 300-600-nm window. Moreover, the direction of the photocurrent could be changed from anodic to cathodic and vice versa by application of the appropriate photoelectrode potential. Photoelectrochemical and spectroscopic studies allowed the elucidation of the mechanism of photocurrent switching. Photoelectrodes composed of folatemodified titanium dioxide may serve as a simple model of optoelectronic switches and may constitute the basis for molecular photoelectronic devices.

    ABSTRACT: Hybrid (n-/p-type) semiconductor electrodes represent a viable strategy for fabrication of wavelength-controlled optoelectronic switches. Four hybrid electrodes (BiVO4/Co3O4, BiVO4/CuO, TiO2/Co3O4, TiO2/CuO) were prepared in the form of random assemblies of nanocrystalline powders on ITO-glass and the wavelength dependence of their photocurrent response was investigated. The former three electrodes exhibited wavelength-controlled switching of photocurrent direction, whereas the latter one showed exclusively cathodic photocurrents. The prerequisite for the switching effect is that the potentials of the valence and conduction band edges of an n-type component are more positive than those of a p-type one. Further key parameters influencing the photocurrent response are the applied potential and the presence of electron and hole scavengers.

    ABSTRACT: Supramolecular chemistry, also known as the chemistry beyond the molecules, provides the best route for molecular nanotechnology, allowing the design of versatile functional nanomaterials conveying the remarkable characteristics of the molecular centers, including their electronic, optical and chemical properties. Synthetic strategies have been successfully developed for the assembly of supramolecular systems encompassing porphyrins, porphyrazines, clusters and polyimine complexes. Their many applications in nanotechnological devices, such as amperometric sensors, smart windows, photoelectrochemical cells and logic gates are dealt with in this article.
