Abstract
An electronic device containing a polythiophene derived from a monomer segment or monomer segments containing two 2,5-thienylene segments, (I) and (II), and an optional divalent linkage D wherein A is a side chain; B is hydrogen or a side chain; and D is a divalent linkage, and wherein the number of A-substituted thienylene units (I) in the monomer segments is from about 1 to about 10, the number of B-substituted thienylene units (II) is from 0 to about 5, and the number of divalent linkages D is 0 or 1.
Claims7
An electronic device containing a polythiophene having a Mn of greater than 2,000 to about 100,000, and derived from a monomer segment or monomer segments consisting of two 2,5-thienylene segments, (I) and (II), and one divalent linkage D
- wherein A is an alkyl side chain containing from 5 to about 25 carbon atoms;
- B is an alkyl side chain containing from 1 to about 4 carbon atoms;
- wherein the number of A-substituted thienylene units (I) in the monomer segments is from about 1 to about 10 and the number of B-substituted thienylene units (II) is from 1 to about 5;
- and the divalent linkage D is selected from the group consisting of arylene containing from about 6 to about 40 carbon atoms, dioxyarene containing from about 6 to about 40 carbon atoms, dioxyalkane containing from about 1 to about 20 carbon atoms, phenylene, tolylene, xylylene, biphenylene, substituted biphenylene, phenanthrenylene, dihydrophenanthrenylene, fluorenylene, dibenzothiophenediyl, dibenzofurandiyl, carbazolediyl, and oligoethylene oxide.
