Patent ID: 7074886

Claim:
A polymer comprising one or more monomeric units having a Formula I, where: R is a substituent on a carbon atom in an aromatic ring, which can be the same or different at each occurrence and is selected from hydrogen, alkyl, aryl, heteroalkyl, heteroaryl, F, â€”CN, â€”OR 1 , â€”CO 2 R 1 , â€”C Ïˆ H Î¸ F Î» , â€”OC Ïˆ H Î¸ F Î» , â€”SR 1 , â€”N(R 1 ) 2 , â€”P(R 1 ) 2 , â€”SOR 1 , â€”SO 2 R 1 , â€”NO 2 , and beta-dicarbonyls having Formula XII; or adjacent R groups together can form a ring selected from 5-membered cycloalkyl, 6-membered cycloalkyl, 5- membered aryl, 6-membered aryl, 5-membered heteroaryl and 6-membered heteroaryl, such that: R 1 is a substituent on a heteroatom which can be the same or different at each occurrence and is selected from alkyl, aryl, heteroalkyl and heteroaryl; and Ïˆ is an integer between 1 and 20, and Î¸ and Î» are integers satisfying Equation A1 below: Î¸+Î»=2Ïˆ+1;â€ƒâ€ƒ(Equation A1); R 2 is a substituent on a carbon atom not in an aromatic ring, which can be the same or different at each occurrence and is selected from hydrogen, alkyl, aryl, heteroalkyl, heteroaryl and â€”C Ïˆ H Î¸ F Î» , with the proviso that the Formula I monomeric unit contains at least one R substituent with the formula â€”C Ïˆ F 2Ïˆ+1 .
