Stabilization of the Oxidation State plus IV in Siloxide-Supported Terbium Compounds

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

The synthesis of lanthanides other than cerium in the oxidation state +IV has remained a desirable but unmet target until recently, when two examples of Tb-IV with saturated coordination spheres were isolated. Here we report the third example of an isolate ...

D-pi-A-Type Triazatruxene-Based Dopant-Free Hole Transporting Materials for Efficient and Stable Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Sanghyun Paek, Cristina Roldán Carmona, Kasparas Rakstys, Hobeom Kim, Cansu Igci

Three donor-pi-bridge-acceptor (D-pi-A)-type organic small molecules coded CI-B1, CI-B2, and CI-B3 are designed, synthesized, and used as dopant-free hole transporting materials (HTMs) for perovskite solar cells (PSCs). The strong electron-donating triazat ...

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) ...

Significance 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 ...

Arene Osmium Complexes with Ethacrynic Acid-Modified Ligands: Synthesis, Characterization, and Evaluation of Intracellular Glutathione S-Transferase Inhibition and Antiproliferative Activity

Paul Joseph Dyson, Tina Riedel, Emilia Paunescu

Four arene osmium complexes were prepared containing derivatives of ethacrynic acid, a potent inhibitor of glutathione Stransferases, either by direct coordination or via N- or P-donor ligands. The complexes were characterized by spectroscopic and analytic ...
