Recent Advances of Electrode Materials Applied in an Electrochromic Supercapacitor Device.

An electrochromic supercapacitor device (ESD) is an advanced energy storage device that combines the energy storage capability of a supercapacitor with the optical modulation properties of electrochromic materials. The electrode materials used to construct an ESD need to have both rich color variations and energy storage properties. Recent advances in ESDs have focused on the preparation of novel electrochromic supercapacitor electrode materials and improving their energy storage capacity, cycling stability, and electrochromic performance.

Facile Preparation of High-Performance Polythiophene Derivative and Effect of Torsion Angle Between Thiophene Rings on Electrochromic Color Change.

The electrochromic phenomenon of conducting polymer is mainly dominated by the π-π* band transition. The π conjugation is influenced by the coplanarity between polymer units, deviations from which can lead to an increased ionization potential and band gap values. In order to investigate the effect of plane distortion angle on electrochromic color in the main chain structure of polymerization, high-performance poly(3,3'-dimethyl-2,2'-bithiophene) (PDMeBTh) with a large plane distortion angle is successfully synthesized in boron trifluoride diethyl etherate (BFEE) by the electrochemical anodic oxidation method.

A novel tetranuclear Cu(ii) complex for DNA-binding and anticancer activity.

A novel tetranuclear Cu(ii) complex (TNC) was successfully synthesized and characterized by X-ray single crystal diffraction. The interaction of the complex with calf thymus DNA (CT-DNA) has been studied by UV-vis absorption titration, fluorescence technology and molecular docking. The results indicated that TNC could bind to the DNA through an intercalative mode.

A simultaneously GSH-depleted bimetallic Cu(ii) complex for enhanced chemodynamic cancer therapy.

A bimetallic Cu(ii) complex as a novel antitumor chemodynamic therapy agent with glutathione (GSH) depletion properties is successfully synthesized and well characterized. In tumor cells, the Cu ions of the complex are reduced to Cu ions by GSH and then catalyzed by the overexpressed HO to generate highly cytotoxic hydroxyl radicals (˙OH) that kill cancer cells. The complex is quickly taken up by cancer cells and distributed in multiple organelles including mitochondria and the nucleus.

A novel Mn-Cu bimetallic complex for enhanced chemodynamic therapy with simultaneous glutathione depletion.

A bimetallic complex, containing Mn(ii) and Cu(ii) moieties, was synthesized for chemodynamic therapy (CDT) of cancer. The complex was capable of generating a hydroxyl radical (˙OH) via a Fenton-like reaction involving a Mn complex, and simultaneously depleting glutathione via a Cu complex induced oxidative reaction, thereby enhancing the efficiency of CDT.

Sodium borohydride-nickel chloride hexahydrate in EtOH/PEG-400 as an efficient and recyclable catalytic system for the reduction of alkenes.

An efficient, safe and one-pot convenient catalytic system has been developed for the reduction of alkenes using NaBH-NiCl·6HO in EtOH/PEG-400 under mild conditions. In this catalytic system, a variety of alkenes (including trisubstituted alkene α-pinene) were well reduced and the Ni catalyst could be recycled.

Rh nanoparticle catalyzed hydroaminomethylation of 1-octene in thermoregulated ionic liquid and organic biphasic system.

Thermoregulated ionic liquid and organic biphasic system composed of ionic liquid [CH3(OCH2 CH2)22N+Et3][CH3SO3-] (abbreviated as IL(PEG1000)) containing IL(PEG1000)-stabilized Rh nanoparticles and organic solvent, which allows for not only highly efficient homogeneous reaction but also an easy biphasic separation, was applied to the hydroaminomethylation of 1-octene for the first time. Under the optimized conditions, the conversion of 1-octene and the amine selectivity were 100% and 90%, respectively. After reaction, the Rh nanoparticle catalyst could be easily separated by simple decantation and reused for four times without evident loss in activity.
