One-pot synthesis of functionalized bis(trifluoromethylated)benziodoxoles from iodine(i) precursors
Jérôme Waser, Xingyu Liu, Nieves Pilar Ramirez Hernandez, Tobias Michael Milzarek
Bis(trifluoromethylated)benziodoxoles (Bx) are broadly used cyclic hypervalent iodine reagents due to their stability and unique chemical properties. However, current methods to access them require several steps and long reaction times, making their synthe ...
2023Lateral Intermolecular Electronic Interactions of Diketopyrrolopyrrole D−π–A Solar Dye Sensitizers Adsorbed on Mesoporous Alumina
Jacques-Edouard Moser, Ulf Anders Hagfeldt, Heewon Bahng
The development of push−pull organic dyes utilizing the donor−(π-conjugated bridge)−acceptor (D−π−A) motif has induced a paradigm shift in the design of efficient nanocrystalline dye-sensitized solar cells (DSSCs), offering control over the aesthetic prope ...
2018Experimental demonstration of the water-holding property of three-dimensional vortices
When injecting dye into a vertical vortex generated by a commercial magnetic stirrer, one finds that dye remains captured around the vortex core over minutes, while it gets mixed with the water outside this region rather rapidly. Thus, considering its hori ...
2018Significance of pi-bridge contribution in pyrido[3,4-b]pyrazine featured D-A-pi-A organic dyes for dye-sensitized solar cells
Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Zhongjin Shen, Yelin Hu, Xiaoyu Zhang
The 3,4-ethylenedioxythiophene (EDOT) pi-bridge is one of the most commonly used building blocks for sensitizers in dye-sensitized solar cells (DSSCs). We investigated its influence on the molecular structure, the photophysical and electrochemical properti ...

Michael Graetzel, Joachim Maier, Alessandro Senocrate
By applying a multitude of experimental techniques including H-1, N-14, Pb-207 NMR and I-127 NMR/NQR, tracer diffusion, reaction cell and doping experiments, as well as stoichiometric variation, conductivity, and polarization experiments, iodine ions are u ...
Wiley-Blackwell2017Unraveling the Dual Character of Sulfur Atoms on Sensitizers in Dye-Sensitized Solar Cells
Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Peng Gao, Thomas Moehl, Joël Teuscher, Aswani Yella, Sadig Aghazada
Cyclometalated ruthenium sensitizers have been synthesized that differ with number of thiophene units on the auxiliary ligands. Sensitizers possessing four (SA25, SA246, and SA285) or none (SA282) sulfur atoms in their structures, were tested in solar cell ...

Shaik Mohammed Zakeeruddin, Ulf Anders Hagfeldt, Jiahuan Zhang, Kazuteru Nonomura, Yan Hao, Yasemin Saygili, Anna Eriksson, Enrico Polanski
Blue and green dyes as well as NIR-absorbing dyes have attracted great interest because of their excellent ability of absorbing the incident photons in the red and near-infrared range region. A novel blue D-pi-A dye (Dyenamo Blue), based on the diketopyrro ...
2016A study of oligothiophene-acceptor dyes in p-type dye-sensitized solar cells
Lei Zhang, Ulf Anders Hagfeldt, Peng Liu
Two new dyes, E1 and E2, equipped with triphenylamine as the electron donor, oligothiophene as the linker and different electron acceptor groups, have been designed and synthesized as photosensitizers for p-type dye-sensitized solar cells (p-DSCs). A syste ...
