Introduction of substituents for tuning the redox properties of benzoate-bridged paddlewheel diruthenium(II,II) complexes: what does the OH group bring?

Benzoate-bridged paddlewheel diruthenium(II,II) complexes ([RuII,II2(RArCO)(L)] (L = axial ligand); [RuII,II2]) exhibit reversible redox activity involving the oxidized species [RuII,III2]. The redox activity can be finely tuned over a broad potential range by altering the substituent R on the benzoate-bridging ligand RArCO. The electronic contributions of the substituents R depend on their type and position, as was empirically demonstrated by Hammett for substituents at the - and -positions.

Ultrafast Luminescence Detection with Selective Adsorption of Carbon Disulfide in a Gold(I) Metal-Organic Framework.

Although a widely used and important industrial chemical, carbon disulfide (CS) poses a number of hazards due to its volatility and toxicity. As such, the development of multifunctional materials for the selective capture and easy recognition of CS is one of the crucial issues. Herein, we demonstrate completely selective CS adsorption among trials involving HO, alcohols, volatile organic compounds (including thiol derivatives), N, H, O, CH, CO, NO, and CO.

Propeller-Shaped Blatter-Based Triradicals: Distortion-Free Triangular Spin System and Spin-State-Dependent Photophysical Properties.

Herein, we report the synthesis and properties of triptycene-based C- and C-symmetric stable triradicals. SQUID magnetometry showed the propeller-shaped triradicals were both an antiferromagnetic equilateral triangle spin system with small spin-spin interactions J/k~-120 K and -106 K, leading to ca. 4/6 coexistence of the doublet/quartet states in thermal equilibrium at room temperature.
