LiBF4‐Induced Rearrangement and Desymmetrization of a Palladium‐Ligand Assembly

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Sylvain Alexandre Marie Sudan

Thirteen palladium-ligand assemblies with different structures and topologies were investigated for the ability to bind lithium ions. In one case, the addition of LiBF4 resulted in a profound structural rearrangement, converting a dincluclear [Pd2L4]2 comp ...

Generalized Synthesis to Produce Transparent Thin Films of Ternary Metal Oxide Photoelectrodes

Kevin Sivula, Liang Yao, Nestor Guijarro Carratala, Florent Alexandre Boudoire, Charles Roger Jean Lhermitte, Annalisa Polo

Developing facile approaches to prepare non-light-scattering ternary oxide thin film photoelectrodes is an important goal for solar water splitting tandem cells. Herein, a novel synthesis route is reported that employs ethylenediaminetetraacetic acid (EDTA ...

Macrocycle synthesis strategy based on step-wise “adding and reacting” three components enables screening of large combinatorial libraries

Christian Heinis, Gerardo Turcatti, Julien Bortoli Chapalay, Alessandro Angelini, Alessandro Zorzi, Jonathan Patrice Vesin, Ganesh Kumar Mothukuri, Sangram Shivdas Kale, Carl Leonard Stenbratt

Macrocycles provide an attractive modality for drug development, but generating ligands for new targets is hampered by the limited availability of large macrocycle libraries. We have established a solution-phase macrocycle synthesis strategy in which three ...

UV and IR Spectroscopy of Transition Metal–Crown Ether Complexes in the Gas Phase: Mn2+(benzo-15-crown-5)(H2O)0–2

Thomas Rizzo, Yoshiya Inokuchi

Ultraviolet photodissociation (UVPD) and IR–UV double-resonance spectroscopy are performed for bare and microhydrated complexes of Mn2+(benzo-15-crown-5), Mn2+(B15C5)(H2O)n (n = 0–2), under cold (∼10 K) gas-phase conditions. Density functional theory (DFT) ...

Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performance

Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Jiyoun Seo, Amita Ummadisingu, Taisuke Matsui

All of the cations currently used in perovskite solar cells abide by the tolerance factor for incorporation into the lattice. We show that the small and oxidation-stable rubidium cation (Rb+) can be embedded into a "cation cascade" to create perovskite mat ...

Laser Spectroscopic Study of Cold Host–Guest Complexes of Crown Ethers in the Gas Phase

Thomas Rizzo, Yoshiya Inokuchi

A laser spectroscopic study on the structure and dynamics of cold host–guest inclusion complexes of crown ethers (CEs) with various neutral and ionic species in the gas phase is presented. The complexes with neutral guest species are formed by using supers ...
