New thermally stable, fluorescent copolymers consisting of fluorenylidene‐linked conjugated oligo( p ‐phenylene) segments are presented. The copolymers have been prepared by the palladium‐catalyzed Suzuki polycondensation method. The copolymers obtained are found to be soluble and easily processable from conventional organic solvents such as chloroform, toluene or tetrahydrofuran, and have been characterized by 1 H and 13 C NMR spectroscopy, FT‐IR spectroscopy and elemental analysis. The degree of polymerization has been estimated by gel permeation chromatography (GPC). The thermal properties of the copolymers were characterized by differential scanning calorimetry (DSC). The optical properties of the polymers have been investigated in solution by UV/VIS spectroscopy.
