Electroluminescence properties of twisted dyad 1,8-naphthalic anhydride derivatives

Several twisted intramolecular charge transfer (TICT) fluorescence dyad compounds containing 1,8-naphthalic anhydride derivatives have been synthesized in this paper, and their electroluminescence properties were observed. It is more important that stronger solid state fluorescence and enhancement fluorescence as well as large Stokes shift due to the TICT process have been observed in these dyad twisted compounds.
