Metal-Organic-Framework-Derived Co3S4 Hollow Nanoboxes for the Selective Reduction of Nitroarenes

Wendy Lee Queen, Emad Oveisi, Daniel Teav Sun, Shuliang Yang, Li Peng, Safak Bulut

MOF-derived Co3S4/CN hollow nanoboxes (CN=nitrogen-doped carbon) was used to catalyze the chemoselective reduction of nitroarenes to anilines under mild reaction conditions with H-2 as the reducing agent. The catalyst provides high conversion efficiencies ...

A hybrid electron donor comprising cyclopentadithiophene and dithiafulvenyl for dye-sensitized solar cells

Michael Graetzel, Chenyi Yi

Two new photosensitizers featured with a cyanoacrylic acid electron acceptor (A) and a hybrid electron donor (D) of cyclopentadithiophene and dithiafulvenyl, either directly linked or separated by a phenyl ring, were synthesized and characterized. Both of ...

Intensification of slow reversible chemical transformation: carboxylation of resorcinol as a case study

Lioubov Kiwi, Charline Berguerand, Anne-Laure Dessimoz

Conjugated kinetic and thermodynamic modeling is suggested as a suitable approach to identify a novel process window (NPW) for the intensification of slow reversible reactions. The aqueous Kolbe-Schmitt synthesis of beta-resorcylic acid is taken as a model ...

Correlating the Lifetime and Fluorine Content of Iridium(III) Emitters in Green Light-Emitting Electrochemical Cells

Mohammad Khaja Nazeeruddin, Julien Edouard Frey

In light-emitting electrochemical cells, the lifetime of the device is intrinsically linked to the stability of the phosphorescent emitter. In this study, we present a series of ionic iridium(III) emitters based on cyclometalating phenylpyridine ligands wh ...

Modulating the Steric, Electronic, and Catalytic Properties of Cp* Ruthenium Half-Sandwich Complexes with β-Diketiminato Ligands

Paul Joseph Dyson, Rosario Scopelliti, Kay Severin, Andrew Douglas Phillips, Katrin Anne Thommes, Dominique Schreiber

Five different types of β-diketiminate ligands, bearing electron-donating to strongly electron-withdrawing substituents, were synthesized and used in the synthesis of Cp* ruthenium complexes (Cp* = η5-C5Me5). One series consists of complexes with a covalen ...

Selective three-phase hydrogenation of aromatic nitro-compounds over β-molybdenum nitride

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

A tetragonal molybdenum nitride (β-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N2 + H2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; PH2=11bar) of a series of para-substitut ...

Selective three-phase hydrogenation of aromatic nitro-compounds over beta-molybdenum nitride

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

A tetragonal molybdenum nitride (beta-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N-2 + H-2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; P-H2 = 11 bar) of a series of para- ...

Substituent Effect on the Meso-Substituted Porphyrins: Theoretical Screening of Sensitizer Candidates for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Xiaoyu Zhang

According to the concepts of attribute axis and attribute coordinate system, porphine and 11 kinds of bridge carbon substituted porphyrins as donors and 9 common acceptors A-I have been designed and calculated at the density functional B3LYP level. The sub ...
