제목 Three-Dimensional Structures Including the Fusion of Chrysene and Spirobifluorene Chromophores for the Development of Deep Blue-OLEDs
초록 A new deep-blue chromophore containing a three-dimensionally (3D) shaped CS core composed of fused chrysene and spirofluorene units is synthesized. A pair of m-terphenyl (TP) units is also substituted onto the CS core at two different sets of positions to form two additional compounds: CS−TPTP and TP−CS−TP. The TP−CS−TP compound showed the highest efficiency with an external quantum efficiency (EQE) of 3.05% and Commission Internationale de L’Eclairage coordinates (CIE) of (0.148, 0.098) corresponding to the emission of blue light. This approach for forming a new chromophore is expected to lead to the development of functional organic materials with excellent characteristics.
