Pure organic molecules which show aggregation-induced emission (AIE) has attracted great interest due to their emerging applications in organic electronics. As typical AIE-active functional moieties are tetraphenylethene (TPE), Triphenylethylene (TriPE), Triphenylbenzene etc. has been investigated because of their facile synthesis and easy structural modifications, and at the same time shown wide applications in Organic light-emitting diodes (OLEDs). OLEDs are the attractive prospect for the development of next generation full color, flat panel displays and lighting technologies, due to their attractive features including wide viewing angle, superior color quality, fascinating flexibility, etc. [1-3] The development of efficient deep blue emitters is of great significance in OLED applications for full-color displays and energy-saving lightings. AIE based Phenanthroimidazole (PI) materials have attracted much attention due to their own facile structural modification at the N1 and C2 positions to produce efficient deep-blue OLEDs satisfying the color purity criteria given by the National Television System Committee (NTSC) (CIE: 0.14, 0.08) and European Broadcasting Union (EBU) (CIE: 0.15, 0.06). In this present study, we have successfully designed and synthesized a series of PI based AIE blue emitters and their theoretical, photophysical and electrochemical properties are investigated in order to study the luminescence behavior.
