Excited State Tuning of Bis(tridentate) Ruthenium(II) Polypyridine Chromophores by Push–Pull Effects and Bite Angle Optimization: A Comprehensive Experimental and Theoretical Study

“…To explore this helical twist of the coordinated ddpd ligand, a solution of [ 2 ][PF 6 ] 2 was treated with the chiral anion [Δ‐tris(tetrachloro‐1,2‐benzenediolato)phosphate(V)] ((Δ‐TRISPHAT) − ) 45. 69 This splits the 1 H NMR resonances of [ 2 ] 2+ (H 2 , H 15 , NH 2 , CH 2 , NCH 3 , CH 3 ; Figure 1; Figure S33, the Supporting Information) into two signal sets (≈1.0:1.3 by integration of 1 H NMR spectrum) revealing the helical chirality of [ 2 ] 2+ . The formation of diasteromeric ion pairs is a result of the electrostatic attraction between the cations and anions leading to a high proximity between [ 2 ] 2+ and the (Δ‐TRISPHAT) − or [PF 6 ] − counterions.…”

Taming the Cationic Beast: Novel Developments in the Synthesis and Application of Weakly Coordinating Anions

“…[170] Thep reparation of the chlorinated analogue [P(O 2 C 6 Cl 4 ) 3 ] À ,e fficient resolution of the enantiomers,a nd demonstration of its configurational stability in solution at room temperature has led to agrowing usage of this class of anion. [175,176] Thes ynthesis of the fluorinated analogue [P(O 2 C 6 F 4 ) 3 ] À has also been reported and the electrochemical properties of both the fluorinated and non-fluorinated anions were investigated in terms of their lithium ion battery capabilities ( Figure 6). [173,174] Furthermore,t he ability to isolate an enantiomerically pure WCA has been utilized for the transfer of chiral information through ion pairing as well as enantiomeric resolution of chiral cations.…”

[177,178] Ther elated lower molecular weight oxalate-containing "BOB" ([B(C 2 O 4 ) 2 ] À ) [179] and so-called "half-BOB" ([F 2 B-(C 2 O 4 )] À ) [180] anions have found an umber of applications as electrolytes for lithium ion batteries and in ionic liquids ( Figure 6).…”

“…The stronger Brønsted acid salt [H(OEt 2 ) 2 ][P(O 2 C 6 Cl 4 ) 3 ] is now accessible, although low‐temperature (−30 °C) handling is required, and has been applied as a single‐component initiator for the carbocationic polymerization of olefins . Furthermore, the ability to isolate an enantiomerically pure WCA has been utilized for the transfer of chiral information through ion pairing as well as enantiomeric resolution of chiral cations . The synthesis of the fluorinated analogue [P(O 2 C 6 F 4 ) 3 ] − has also been reported and the electrochemical properties of both the fluorinated and non‐fluorinated anions were investigated in terms of their lithium ion battery capabilities (Figure ) …”

Synthesis, characterization, X-ray structure and DFT calculations of a bistridentate Co(III) complex based on the 2,6-bis(8′-quinolinyl)pyridine ligand

“…This allows for six-membered chelate rings to be formed, leading to more octahedral-like complexes. Complexes containing this ligand are known for Re I , Ru II and Mn I [2][3][4][5][6][7]. However, to our knowledge, this report is the first study of a Co complex with this ligand.…”
