Abstract:
1. A process for preparing fluorene polymers having perfluoroalkyl groups, the steps comprising: (A) forming a polymer having at least one monomeric unit having a Formula I or a polymer having at least one monomeric unit having a Formula I and monomeric unit having a Formula I(a):  where: R is a substituent on a carbon atom in an aromatic dng, which can be the same or different at each occurrence and is selected from hydrogen, alkyl, aryl, heteroalkyl, heteroaryl, F, —CN, —OR  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 ψ is an integer between 1 and 20, and θ and λ are integers satisfying Equation A1 below: R R δ is 0 or an integer from 1 to 12; and (B) treating the polymer with a perfluoroalkylating reagent selected from (i) a perfluoroalkyl iodide and (ii) a perfluoroalkylsulfonyl chlodde in the presence of a ruthenium(ll) catalyst; with the proviso that, after treating the polymer with the perfluoroalkylating reagent, the polymer contains at least one R substituent with the formula —C
