Patent ID: 7094902

Claim:
A monomer having the structure of Formula IV wherein each D is a reactive group independently selected from chlorine, bromine, iodine, boronic acid, and boronic ester; wherein —Ar 1 (E y ) a - is selected from Formulas CLXV and CLXVI wherein R y is independently in each case fluoro, C 1-20 fluoroalkyl, C 1-20 perfluoroalkyl, C 1-20 alkyl, C 1-20 alkenyl, C 6-20 aryl, C 3-20 heteroaryl, or C 1-30 hydrocarbyl containing one or more S, N, O, P, or Si atoms; n is 0, 1, or 2; a is 1 or 2; Ey is Formula III where X is selected from —O—, —S—, and —N(R 1 )— wherein R 1 is alkyl, aryl, heteroaryl, or heteroalkyl; wherein each R 2 is independently alkyl, alkenyl, alkoxy, fluoro, aryl, fluoroalkyl, heteroalkyl, or heteroaryl; wherein b is 0, 1,or 2; wherein Ar 2 is a carbocyclic aryl group selected from phenyl, biphenyl, naphthyl, anthracenyl, fluorenyl, 9-silafluorenyl, spirobisfluorenyl, dihydrophenanthrolinyl, dihydropyrenyl, tetrahydropyrenyl, pyrenyl, and perylenyl; and wherein Ar 2 is unsubstituted or substituted on one or more of the aromatic rings with one or more groups selected from alkyl, alkenyl, alkoxy, fluoro, aryl, fluoroalkyl, heteroalkyl, heteroaryl, alkyloxadiazolyl, aryloxadiazolyl, alkyltriazolyl, aryltriazolyl, and hydrocarbyl containing on or more S, N, O, P, or Si atoms.
