New Multichromophoric Ligand for Light Harvesting
Light-harvesting antennae are of great importance for the development of efficient solar cells. Multichromophoric systems capable of harvesting light are of interest as they can be used in multicomponent systems in which the different chromophores are in close contact to favor energy and/or electron transfer, so that the excitation energy can be funneled to a specific acceptor. If one of these chromophores is also a good ligand for metal ions, new interesting properties can arise in a supramolecular system, such as control of the energy/electron transfer processes by changing the metal ion or the ability to generate supramolecular architectures and coordination polymers. To find out more about this subject read the paper by Marc Gingras, Aix-Marseille Université, France, Giacomo Bergamini, University of Bologna, Italy, and co-workers.

- Stoichiometrically Controlled Revocable Self-Assembled “Spiro” versus Quadruple-Stranded “Double-Decker” Type Coordination Cages
Sreenivasulu Bandi, Dr. Amlan K. Pal, Prof. Dr. Garry S. Hanan and Prof. Dr. Dillip Kumar Chand
Article first published online: 19 AUG 2014 | DOI: 10.1002/chem.201403808
Molecular double-decker cages: The simple combination of PdII with the tris-monodentate ligand bis(pyridin-3-ylmethyl) pyridine-3,5-dicarboxylate, L, at ratios of 1:2 and 3:4 demonstrated the stoichiometrically controlled formation of a “spiro-type” Pd1L2 macrocycle and a quadruple-stranded “double-decker” Pd3L4 cage, respectively. The architecture of the cage is a fresh design that has two compartments that can accommodate two units of fluoride, chloride or bromide ions, one in each enclosure. However, entry of iodide is altogether restricted.

1,2-1,2-Testing: Novel N,O-chelated borenium cations react with 3-hexyne to give trisubstituted alkenes as a rare example of a transition metal-free 1,2-carboboration (see figure).
- Multifunctional Ag-Decorated Porous TiO2 Nanofibers in Dye-Sensitized Solar Cells: Efficient Light Harvesting, Light Scattering, and Electrolyte Contact
Sun Hye Hwang, Hee Song, Jungsup Lee and Prof. Jyongsik Jang
Article first published online: 19 AUG 2014 | DOI: 10.1002/chem.201305071
Solar power: Silver-decorated porous TiO2 nanofibers (NFs) with high surface area, enhanced light scattering, enlarged interpore connections between the NFs in a photoanode film, and localized surface plasmon resonance (see figure) result in an improved power conversion efficiency in dye-sensitized solar cells from 6.2 to 8.8 % (42 % enhancement) relative to pure TiO2 NFs.
- An Abnormal N-Heterocyclic Carbene–Carbon Dioxide Adduct from Imidazolium Acetate Ionic Liquids: The Importance of Basicity
Zsolt Kelemen, Barbara Péter-Szabó, Dr. Edit Székely, Dr. Oldamur Hollóczki, Dzmitry S. Firaha, Prof. Dr. Barbara Kirchner, Dr. József Nagy and Prof. Dr. László Nyulászi
Article first published online: 18 AUG 2014 | DOI: 10.1002/chem.201402912
Unexpected adducts: The highly basic conditions in the 1-ethyl-3-methylimidazolium acetate ionic liquid, which are further facilitated by the extraction of the acetic acid by-product in the supercritical CO2 phase, allow the formation of an abnormal NHC–CO2 adduct at temperatures above 125 °C.

Fateful attraction: Easily processable Tb3+ and Dy3+ double-decker tetraazaporphyrin (TAP) complexes exhibit single-ion magnetic behavior with large barriers for magnetization reversal (see figure). The smaller skeleton of TAPs compared to the related phthalocyanines means the presented single-molecule magnets are highly soluble and readily sublimed.
