Charge transporting material for optoelectronic and/or photoelectrochemical devices
Michael Graetzel, Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Paul Gratia, Inés Garcia Benito
The present invention relates to an optoelectronic and/or photoelectrochemical device comprising at least one organic-inorganic perovskite as sensitizer and at least one compound of formula (I) comprising one benzotrithiophene core Q, wherein each thiophen ...
2017In Situ Tethering Strategies for the 3-Component Synthesis of Vicinal Amino Alcohols and Diamines via Pd-Catalyzed Carboetherification and Carboamination
Vicinal amino alcohols and diamines are privileged motifs in organic chemistry. As such, they have been targets of choice for exploring and developing novel and more efficient strategies in organic synthesis. In this context, the difunctionalization of ole ...
EPFL2017Piezoelectric softening by Nb substitution in (Ba,Pb)ZrO
Nava Setter, Nicola Marzari, Dragan Damjanovic, Alberto Biancoli, David Bahati
Donor doping is commonly applied for softening of the piezoelectric and dielectric properties and facilitation of polarization switching in the ubiquitous Pb(Zr,Ti)O-3 [PZT] ceramics. The origin of the donor-dopant effects is not entirely clear. (Pb,Ba)ZrO ...
Wiley-Blackwell2017Pyridyl- and Picolinic Acid Substituted Zinc(II) Phthalocyanines for Dye-Sensitized Solar Cells
Mohammad Khaja Nazeeruddin, Jun Ho Yum, Aravind Kumar Chandiran
A series of tri-tert-butyl zinc(II) phthalocyanines (Pcs) substituted with pyridyl, carboxyl, or picolinic acid anchoring groups on the periphery were prepared. Photovoltaic (PV) studies on these dyes were carried out revealing some interesting features. I ...
Wiley-VCH Verlag2017Substituent effects on the relative rates and free energies of ortho-lithiation reactions: families of fluorobenzenes as the substrates
2-, 3- and 4-substituted fluorobenzenes and 5-substituted 1,3-difluorobenzenes were metalated with sec-butyllithium (LIS) and with lithium 2,2,6,6-tetramethylpiperidide (LiTMP) under irreversible conditions in order to determine the rates of reaction relat ...
Arkat Usa Inc2015Zinc-gold cooperative catalysis for the direct alkynylation of benzofurans
The direct alkynylation of benzofurans was achieved for the first time using the hypervalent iodine reagent 1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX) based on the cooperative effect between a gold catalyst and a zinc Lewis acid. H ...
2013Electrical Properties of Nb-, Ga-, and Y-Substituted Nanocrystalline Anatase TiO2 Prepared by Hydrothermal Synthesis
Michael Graetzel, Aravind Kumar Chandiran
Nanocrystalline anatase titanium dioxide powders were produced by a hydrothermal synthesis route in pure form and substituted with trivalent Ga3+ and Y3+ or pentavalent Nb5+ with the intention of creating acceptor or donor states, respectively. The electri ...
