There are provided electrically conducting polymer compositions comprising an electrectically conductive polymer or copolymer and an organic solvent wettable fluorinated acid polymer. Electrically conductive polymer materials are derived from thiophene, pyrrole, aniline and polycyclic heteroaromatic precursor monomers. Non-conductive polymers derived from alkenyl, alkynyl, arylene, and heteroarylene precursor monomers. The organic-solvent wettable fluorinated acid polymer is fluorinated or highly fluorinated and may be colloid-forming. Acidic groups include carboxylic acid groups, sulfonic acid groups, sulfonimide groups, phosphoric acid groups, phosphonic acid groups, and combinations thereof. The compositions can be used in organic electronic devices.

摘要:
The invention provides methods for the application of active materials onto active surfaces useful in organic electronic devices. The methods of the invention include selecting a liquid composition including an active material and a suitable liquid medium whereby when the liquid composition is deposited on the desired active surface it has no greater than about a 40° contact angle; treating the active surface to raise its surface tension before the deposition of a liquid composition containing the desired active material is deposited thereon; and combination thereof. The invention also provides organic electronic devices having at least two active layers, wherein at least one active layer comprises an active material that was deposited using at least one practice of the method of the invention.
摘要:
Hexafluoroisobutylene and its higher homologs are easily reacted with SO3 to give fluorosulfates of the formula CH2═C(R)CF2OSO2F, wherein R is a linear branched or cyclic fluoroalkyl group comprised of 1 to 10 carbon atoms and may contain ether oxygen. These compounds react under mild conditions with many nucleophiles to give CH2═C(R)CF2X, where X is derived from the nucleophile. This reaction provides a route to many substituted hexafluoroisobutylenes, which copolymerize easily with other fluoro- and hydrocarbon monomers such as vinylidene fluoride and ethylene.
