摘要:
Novel conjugated stilbenylene polymers are disclosed having non-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5-dimethyl stilbene, e.g. 2,5-(4' -methoxy)-stilbene dimethylene bis-(tetramethylene sulfonium bromide), with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the stilbenylene vinylene polymer, e.g. poly(2,5-(4'-methoxy)stilbenylene vinylene).
摘要:
Second-order nonlinear optical polymeric films, including alternating monlecular layers of two head-to-head, mainchain, amphophilic, chromophoric polymers, one polymer having the electron donating end of the chromophore attached to hydrophilic groups, and the other polymer having the electron donating end of the chromophore attached to hydrophobic groups, and methods of fabricating the films for use in optonics.
摘要:
A supercapacitor comprising a poly(3,4-ethylendioxythiophene) (PEDOT) and poly(3,4-propylenedioxythiophene) (PProDOT) as electrode couples for the capacitor and a pair of gel electrolyte layers disposed between the electrodes. The gel electrolytes are separated by a battery paper and are selected from a group consisting of a lithium salt and an organic electrolyte.
摘要:
Processible chromophoric polymers having nonlinear optical properties and wherein the chromophore is present in and is a part of the polymer backbone, including substantially all of the monomer or repeat units, with the dipole moments pointing in the same direction (head-to-tail) along the polymer backbone. Such polymers include phenylene, phenylene vinylene, stilbenylene, phenyl piperdine, and coumarin polymers.
