Abstract:
The invention provides novel conjugated polymers comprised of arylamine-substituted poly(arylene vinylenes). The polymers have the general structure (I)wherein: Ar is arylene, heteroarylene, substituted arylene or substituted heteroarylene containing one to three aromatic rings; R1 is an arylamine substituent having the formula -Ar1-N(R4R5) wherein Ar1 is as defined for Ar and R4 and R5 are independently hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, or substituted heteroatom-containing hydrocarbyl, or together form a cyclic group; and R2 and R3 are independently selected from the group consisting of hydrido, halo and cyano, or may be as defined for R4 and R5, or may together form a triple bond. Monomeric precursors and methods of synthesizing the precursors are also provided, as are electroluminescence and other devices containing a polymer of the invention.
Abstract:
PURPOSE: To achieve a prompt response by providing a substrate with an opening, a gas transmission detection electrode, and an additional electrode that contacts an electrolyte and is electrically insulated from the detection electrode and enabling a gas to be analyzed to reach the electrolyte at a gas phase. CONSTITUTION: A passage 18 is formed between surfaces 14 and 16 of a substrate 12, a gas transmission detection electrode 20 is arranged across the passage 18, and an electrolyte 26 is brought into contact with a dielectric layer 22 and a surface side 21 of the electrode 20. Also, a porous member 30 is arranged closer to the electrode 20 within the passage 18, at the same time a counter electrode 24 is arranged so that it contacts the electrolyte 26 and is insulated from the electrode 20, and a capsule is formed by a means 28. Then, for responding to various kinds of gas-shaped objects, the structure of the electrolyte 26 and the size of a hole in the electrode 20 are selected and a gas to be analyzed is passed through the hole of the electrode 20 in gaseous phase, thus achieving an extremely fast response time and a long life.
