Abstract:
1. 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 wherein Ar′ may optionally be fused with one or more groups selected from phenyl, heteroaryl, or Cy 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 wherein Cy wherein each of X 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 wherein R 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]:
