258 results about "Organic anion" patented technology

Organic anions are chemically heterogeneous substances possessing a carbon backbone and a net negative charge. Organic anions are conjugate bases of organic acids. The following table lists some of the organic anions and their conjugate acids which are substrates of the organic acid transporter (OAT) family of transmembrane proteins.

Electrically active polymer compositions and their use in efficient, low operating voltage, polymer light-emitting diodes with air-stable cathodes

The addition of a highly polarizable additive such as an organic anionic surfactant to an electrically active polymer improves the electrical properties of the polymer. When such an additive is added to an electroluminescent organic polymer this mixture can be used in diodes having an anode contacting a layer of this mixture as the active light-emitting layer and an air-stable metal cathode having a work function larger than 4 eV. The external efficiency and brightness versus voltage are significantly improved compared to results obtained with the same electroluminescent polymer used alone with high work function (>4.0 eV) metal cathodes. Specifically, device performance with indium / tin-oxide (ITO) as the anode, poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene), MEH-PPV, as the electroluminescent polymer, lithium nonylphenoxy ether sulfate as the surfactant additive and aluminum as the cathode is comparable to or better than that obtained with high performance devices using calcium as the cathode.

In-situ co-precipitation synthesis method for organic silane grafted hydrotalcite with controllable interlayer spacing

The invention discloses an in-situ co-precipitation synthesis method for organic silane grafted hydrotalcite with a controllable interlayer spacing. Compared with a traditional co-precipitation hydrotalcite synthesis method, the in-situ co-precipitation synthesis method is characterized in that the height of an interlayer space of hydrotalcite is regulated and controlled by the aid of an intercalation effect of surfactant; and the affinity of the surface of minerals is effectively improved by the aid of in-situ condensation of Si-OH generated by hydrolysis of organic silane and hydroxyl on the surface of the clay mineral while hydrotalcite crystal is formed, accordingly, usage of the surfactant is controlled, potential environmental threads including desorption of the surfactant and the like are reduced, reduction of stability and homogeneity of a composite material is also decreased, and the like. Raw materials required by the synthesis method are easily accessible, operation is simple and feasible, and the obtained organic silane grafted hydrotalcite has an important application value in fields such as clay-based nano-composite materials, repair of organic anion environmental pollutant, halogen-free flame retardant and the like.
