Two kinds of deep blue emission materials (** and *** )were synthesized by reduction
coupling Method. The characteristic of the two materials have been studied by UV-vis
absorption spectra, thermogravimetric analysis(TGA), differential scanning calorimetry(DSC)
and fluorescence spectroscopy. The two materials emit strong blue fluorescence under the
excitation of UV light. The induction of Br ion may induce the red-shifted 15 nm of absorption
in the UV-visible light range. UV absorption spectra show the absorption energy of complexes
mostly from ligands.
