    Optical, photophysical, electrochemical and photoelectrical properties of novel soluble low-bandgap fluorene – thienothiadiazole based copolymers and luminescent fluorene – carbazole copolymers, were studied. Fluorene – thienothiadiazole copolymers possess low bandgap, high electron affinity and exhibit reversible electrochromic behaviour. Spectroelectrochemical study was performed and optical switching demonstrated. Photovoltaic devices made of blends of copolymers and fullerene derivative [60]PCBM with the power conversion efficiency 2–3% were prepared. On the other hand, the fluorene-carbazole copolymers exhibit blue photoluminescence with high quantum efficiency in solution and also in thin films. Light-emitting devices with intensive broad bluish-green-white emission were fabricated.
