Abstract

Novel, soluble poly(9,9-dialkylfluorene)/poly(2-alkylaniline) block copolymers were synthesized following a three-step synthetic procedure: (i) aryl-aryl coupling of alkylated dibromofluorenes and fluorene diboronic esters according to Suzuki in the presence of 4-nitrobromobenzene as a monofunctional end-capping reagent, (ii) reduction of nitrophenyl to aminophenyl functions with H2/Pd/C and (iii) subsequent oxidative condensation with 2-undecylaniline. The colored conjugated-conjugated block copolymers were characterized by means of GPC, NMR and UV-Vis spectroscopy.
