The polymers were synthesized by employing a slightly modified Suzuki coupling polymerization reaction and condensation polymerization utilizing the Knoevenagel reaction. The resulting polymers showed good solubility in chloroform. The energetic positions of the band edges were determined by cyclic voltammetry. The synthesized polymers were characterized by using spectroscopic techniques such as UV-Vis and 1H- NMR. The presented polymers exhibited emission of blue to red colors.en9,9-disubstituted fluorenes and cyanovinylenesThesis
