Claim:
A method for preparing a polymer, comprising a. providing a monomer of general formula [1]: wherein Ar′ is selected from phenyl and heteroaryl, and independently substituted with one or more groups independently selected from C1-C18 alkyl, C1-C18 alkoxy, C1-C18 alkylamino, C1-C18 dialkylamino, Cy 1 , Cy 1 -(C1-C18 alkyl)-, Ar 1 , and Ar 1 —(C1-C18 alkyl)-; wherein Ar′ may optionally be fused with one or more groups selected from phenyl, heteroaryl, or Cy 1 ; wherein two or more substituents on Ar′ may optionally be covalently bonded to form a 3- to 17-membered cycloalkyl or, together with 1-2 heteroatoms, comprise a 4- to 17-membered heterocycloalkyl; wherein Ar 1 is selected from phenyl and heteroaryl, and independently substituted with 0, 1, 2, 3, or 4 groups independently selected from C1-C18 alkyl, C1-C18 alkoxy, C1-C18 alkylamino, and C1-C18 dialkylamino; wherein Cy 1 is selected from C3-C18 cycloalkyl and C2-C17 heterocycloalkyl, and substituted with 0, 1, 2, 3, or 4 groups independently selected from C1-C18 alkyl, C1-C18 alkoxy, C1-C18 alkylamino, and C1-C18 dialkylamino; and wherein each of X 1 and X 2 is independently selected from halogen, triflates, nonaflates, fluorosulfonates, tosylates, mesylates, nitrates, phosphates, oxonium ions, diazonium salts, ammonium salts, alcohols, and ethers; b. providing a monomer of general formula [2]: wherein Ar is selected from phenyl, heteroaryl, fused aryl, fused heteroaryl, and an aryl fused with a heteroaryl; and independently substituted with 0, 1, 2, 3, or 4 groups independently selected from C1-C18 alkyl, C1-C18 alkoxy, C1-C18 alkylamino, and C1-C18 dialkylamino; and wherein each of R 5 and R 6 is independently selected from C1-C18 alkyl, C1-C18 alkoxy, C1-C18 monoalkylamino, C1-C18 dialkylamino, Cy 1 , Cy 1 -C1-C18 alkyl)-, Ar 1 , Ar 1 —(C1-C18 alkyl)-, —(C1-C18 alkyl)-(C═O)R 7 , —(C1-C18 alkyl)-(C═O)OR 7 , —(C1-C18 alkyl)-S(O) m R 7 , —(C═O)R 7 , —(C═O)OR 7 , and —S(O) m R 7 ; and wherein R 7 is selected from C1-C18 alkyl, C1-C18 alkoxy, C1-C18 monoalkylamino, C1-C18 dialkylamino; and c. reacting the monomer of formula [1] and monomer of formula [2] in the presence of a transition metal catalyst under conditions effective to form a polymer comprising “n” repeating units of poly formula [IV]:
