ChemPhysChem 06/2014: Special issue on hybrid organic–inorganic photovoltaics

Issue 6 is a special issue on hybrid organic–inorganic photovoltaics, published on the occasion of Michael Grätzel's 70th birthday. It has been guest edited by M. K. Nazeeruddin, J. Bisquert, and S. Ahmad and includes a selection of invited contributions in many interesting areas. In a Review, E. M. J. Johansson, H. Rensmo, and colleagues describe the use of X-ray-based spectroscopic methods to study the atomic and electronic structures of interfaces in dye-sensitized solar cells (DSSCs). The Article by N.-G. Park et al. evaluates the limiting factors affecting the photovoltaic performance of TiO2 films in DSSCs. In the same section, M. Abrahamsson, W. B. Heuer, G. J. Meyer and co-workers present high-extinction-coefficient Ru sensitizers that promote hole transfer on nanocrystalline TiO2. In the Communications section, R. Li, P. Wang at al. show that it is possible to tune the charge-transfer dynamics of sensitized solar cells by altering the self-organization of dyes on titania using dyeing solvents. Finally, T. Miyasaka and A. Ishii describe a metallocene molecular complex as visible-light absorber for high-voltage organic–inorganic hybrid photovoltaic cells (see picture).

  1. Does Excited-State Proton-Transfer Reaction Contribute to the Emission Behaviour of 4-Aminophthalimide in Aqueous Media?

    Dr. Dinesh Chandra Khara, Sanghamitra Banerjee and Prof. Anunay Samanta

    Article first published online: 17 APR 2014 | DOI: 10.1002/cphc.201400078

    Insight into photophysics: The time-resolved and time-integrated fluorescence response of 4-aminophthalimide and its derivative does not indicate photoinduced solvent-mediated intramolecular proton transfer in protic media. Two distinct types of hydrogen-bonded complex of the molecule with the solvent are identified and a new explanation for the solvent isotope effect is suggested.

  2. Reversible Chemical Reactions for Single-Color Multiplexing Microscopy

    M.Sc. Dominik Brox, Dr. Michael Schwering, Dr. Johann Engelhardt and Dr. Dirk-Peter Herten

    Article first published online: 17 APR 2014 | DOI: 10.1002/cphc.201402012

    Taking it back: Reversible chemical reactions can be used to extend the number of imaging channels in fluorescence microscopy. The feasibility of this complementary approach is demonstrated experimentally by imaging four different structures in fixed cells in only two different spectral channels. In addition to aberration-free overlay of microscopic images, its potential for reversible saturable optical fluorescence transition techniques is discussed.

  3. Regio- and Stereospecificity in the Oxygenation of Arachidonic Acid Catalyzed by Leu597 Mutants of Rabbit 15-Lipoxygenase: A QM/MM Study

    Dr. Reynier Suardíaz, Dr. Laura Masgrau, Prof.Dr. José M. Lluch and Prof. Dr. Àngels González-Lafont

    Article first published online: 17 APR 2014 | DOI: 10.1002/cphc.201402045

    Mutant powers: Quantum mechanics/molecular mechanics are used to analyze the effects of mutation of Leu597 by Val and Ala in the peroxidation of arachidonic acid catalyzed by rabbit 15-lipoxygenase. Mutation of bulky Leu597 to a shorter Val residue diminishes the regiospecificity and maintains stereospecificity, but mutation to Ala, a residue even shorter than Val, enhances regiospecificity and inverts stereospecificity.

  4. Self-Propelled Janus Mesoporous Silica Nanomotors with Sub-100 nm Diameters for Drug Encapsulation and Delivery

    Mingjun Xuan, Jingxin Shao, Dr. Xiankun Lin, Dr. Luru Dai and Prof. Qiang He

    Article first published online: 16 APR 2014 | DOI: 10.1002/cphc.201402111

    Drugs in motion: Self-propelled Janus mesoporous silica nanomotors with diameters of sub-100 nm are presented. This new active delivery system combines an autonomous nanomotor and a smart cargo into an integrated system and may be helpful in dealing with current nanoparticle drug-delivery system obstacles (see picture).

  5. Study of Carbamate-Modified Disiloxane in Porous PVDF-HFP Membranes: New Electrolytes/Separators for Lithium-Ion Batteries

    Steffen Jeschke, Dr. Monika Mutke, Dr. Zhongxiang Jiang, Dr. Burkhard Alt and Prof. Hans-Dieter Wiemhöfer

    Article first published online: 15 APR 2014 | DOI: 10.1002/cphc.201400065

    Thumbnail image of graphical abstract

    Soaked through: A porous poly(vinylidene fluoride–hexafluoropropylene) (PVDF-HFP) membrane soaked in a liquid electrolyte containing a carbamate-modified disiloxane and lithium bis(trifluoromethane)sulfonimide (LiTFSI, see picture) results in gel electrolyte membranes, which can be analyzed by using a broad variety of experimental methods.
