Co-polymerization leads to materials with either different spectroscopic properties or different charge and excited - states, which are affected by the relative order of the monomers frontier energy levels. The photoluminescence and the electroluminescence depend not only on the nature of the copolymer units but also on their arrangement along the polymer backbone. Conjugated alternating donor-acceptor type copolymers generally show single photoluminescence bands whereas random co-polymer have a tendency to show dual emission from wider and narrower band gap domains. Although diverse copolymers have been developed to tune the emission color but systematic studies on the effects of incorporating different monomer units into oligo or polyfluorene chains are still lacking .This approach can give valuable insights into fundamentals aspects of the physics involved in these system and can also provide guidelines to develop new strategies for practical applications .Fluorene based copolymers has been developed by incorporating a new electron deficient moiety dibenzothiophene-S,S-dioxide.
