The efficient synthesis and photophysical propel ties of a series of ambipolar donor acceptor donor Systems is described where the acceptor is dibenzothrophene S,S-dioxide and the donor is fluorene, carbazole or arylamine The systems exhibit intramolecular charge transfer (ICT) states (available ICT character strengths)}editing to fluorescence emission ranging from deep blue to green with model ate to high photoluminescence quantum yields The emission properties can be effectively tuned by systematically changing die position of substitution on both donor and acceptor units (which affects the extent of conjugation) and the redox potentials of the donor units The results are supported by cyclic voltammetric data and TD-DFT calculations
