Synthesis and Properties of a Blue Bipolar Indenofluorene Emitter Based on a D-π-A Design
摘要:
Through a rational design, a novel Donor-Acceptor pi-conjugated (D-pi-A) blue fluorescent indenofluorene dye, DA-DSF-IF, has been synthesized for application In single-layer Small Molecule Organic Light Emitting Diodes (SMOLEDs). This new blue emitter possesses bipolar properties as well as good morphological and emission color stabilities and has been successfully used in a blue emitting single-layer SMOLED, with performances impressively magnified compared to a nonbipolar indenofluorene emitter.
