Abstract
A family of conjugated polymers based on 9,9-disubstituted fluorenes and
cyanovinylenes were reported. 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.
