A Fused Donor−Acceptor System Based on an Extended Tetrathiafulvalene and a Ruthenium Complex of Dipyridoquinoxaline

Abstract

An application of the Horner-Wadsworth-Emmons reaction carried out on a ruthenium compound as the electrophilic precursor is described for the synthesis of fused donor-acceptor system 1 based on an extended tetrathiafulvalene and a ruthenium complex of dipyridoquinoxaline units.

Towards Artificial Photosynthesis of CO2‐Neutral Fuel: Homogenous Catalysis of CO2‐Selective Reduction to Methanol Initiated by Visible‐Light‐Driven Multi‐Electron Collector

“…The treatment of [(bpy) 2 Ru(P)] 2+ (bpy=2,2′‐bipyridine, P=benzodipyrido[3,2‐ a :2′,3′‐ c ]phenazine) with 5 equivalents of sodium persulfate in refluxing aqueous solution for 6 h gave the desired complex ( 1 ) with PF 6 − counteranions in 68 % yield. The structure was confirmed by 1 H NMR spectroscopy and the spectrum was completely in accordance with that reported previously 20. The PF 6 − counteranions were exchanged for Cl − ions to make the complex water‐soluble.…”

Synergistic Effect of Hydrogen Bonding and π-π Stacking Enables Long Cycle Life in Organic Electrode Materials

“…Large-scale mining of metal ores is environmentally and economically costly and ultimately unsustainable. 1,2 The rich redox chemistry of organic molecules offers an intriguing alternative to transition metal-based cathode materials, [3][4][5][6][7][8] as organic electrode materials (OEMs) benefit from abundant starting materials and unparalleled synthetic modularity that allow for systematic optimization of cycling performance.…”

“…With excellent cycle stability and rate capability, 3 drastically outperforms 1 and 2, as well as many other quinone-based OEMs. 1,[3][4][5][6][7][8] To understand the structural features of 3 that enable its enhanced galvanostatic cycling, the solid-state structure of 3 was studied by powder X-ray diffraction (PXRD) at the Advanced Photon Source (Chicago, IL, λ = 0.4569 Å). Rietveld refinement of the PXRD data using GSAS-II software 44 revealed that 3 packs in a P21/n space group with a unit cell volume of 1045 Å 3 (Z = 4).…”

Metal Complexes Based on Tetrathiafulvalene‐Fused π‐Extended Schiff Base Ligands – Syntheses, Characterization, and Properties

“…been attached to the TTF moiety, and their corresponding electroactive complexes have been reported. [9][10][11][12][13][14] Among them, pyridine and bipyridine groups have attracted the most attention due to their well-known coordination ability to different metal ions. [15][16][17][18][19][20][21] In order to obtain new electroactive complexes with intriguing structures and interesting properties, we have studied several new π-extended Schiff base pyridine ligands with different coordinated orientations.…”

“…The appropriate linkages or effective bridges are important to link the paramagnetic centers and conduct electrons. A variety of mono‐ or polydentate organic ligands for metal coordination havebeen attached to the TTF moiety, and their corresponding electroactive complexes have been reported 9–14. Among them, pyridine and bipyridine groups have attracted the most attention due to their well‐known coordination ability to different metal ions 15–21…”
