Abstract (300 words maximum)

Azobenzene (azo) and azaborine are fascinating compounds because of their valuable and interesting optical properties making them suitable to be utilized in many optoelectronic devices. We have designed, synthesized and will investigate a series of novel non-conjugated thermally stable mono-azo-azaborine chromophores by linking the two chromophores (azo and azaborine) together as easily tunable high-luminescent organic materials. The substituent effects on the combined chromophores will be investigated by the addition of electron –withdrawing and –donating moieties to the core of the azobenzene. We will investigate the role of the electron –donating and –withdrawing substituents on the HOMO and LUMO energies to aid in understanding the fluorescence tunability. We will also investigate the effect of the photoinduced isomerization of the azobenzene on the aggregation and fluorescence of the mono-azo-azaborine chromophore.
