Preparation and properties of Triazine based Streptocyanines
A new series of bistriazine-based streptocyanines has been selectively prepared. 1D- and 2D-DNMR spectroscopy and computational calculations have shown the presence of a Cl … H bond. UV–vis and fluorescence spectroscopy show that streptocyanine-based bistriazines are violet-blue emitters and large Stokes shifts of more than 6000 cm−1 were observed. The title compounds showed interesting properties which have potential for use in optoelectronic devices.
