    Helping solar cells go natural: Pheophytin- or pyropheophytin-capped carbon dots (CDs) are employed as sensitizers in nanocrystalline-TiO2-based solar cells. The natural-dye/CD hybrids were synthesized by means of a single-step hydrothermal treatment of celery leaf extracts.

  2. Protonation-State-Driven Photophysics in Phenothiazinium Dyes: Intersystem Crossing and Singlet-Oxygen Production

    Dr. Angela Rodriguez-Serrano, Dr. Martha C. Daza, Dr. Markus Doerr, Dr. Jörg Tatchen and Prof. Dr. Christel M. Marian

    Blame it on the proton! The interplay between the ground and excited states of diprotonated (TH22+) and neutral imine (T) forms of thionine (TH+) is presented. The (de)protonation of TH+ is shown to effect ISC processes and quench singlet-oxygen (1O2) production.

  3. An Acid-Responsive Single Trichromatic Luminescent Dye That Provides Pure White-Light Emission

    The butterfly effect: A p-phenylene-bridged bipyrrole bearing N-alkylimino groups exhibits a trichromatic color change in fluorescence from blue to orange to green upon mono- and diprotonation of the imino groups (see figure). The compound demonstrates pure white-light emission as a result of a dynamic equilibrium between the three states.

  4. Efficient Photocatalytic Hydrogen Generation from Water over CdS Nanoparticles Confined by Alumina Matrix
