Our research team have already synthesized a novel blue emission materials based on a type of dual core concept(TP-AP-TP). Here in, We synthesized two new blue emission materials based on this dual core system using different side groups.(DSF-AP and DCP-AP) especially, The side groups of these materials are synthesized using another chromophores. These materials were synthesized through boronylation and Suzuki coupling reactions. DSF-AP exhibited an PLmax value of 443nm and DCP-AP exhibited an PLmax value of 446nm. The dual core chromophore materials had narrow PL and EL spectra. The thermal properities of these materials were caracterized with TGA/DSC. The electro-optical properties of these materials were characterized with cyclic voltammetry (CV), and UV-visible and photoluminescence (PL) spectroscopy. Moreover, multilayered EL devices were fabricated using these materials. |
