Abstract
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.
