Two Novel Tetrahedrally Silicon-Based Benzimidazole Derivatives: Potentials as Blue Emitters for OLEDs
Two novel silicon-centered benzimidazole derivatives, Bis(4-(benzimidazol-1-yl)phenyl) dimethylsilane (1) and Bis(3-(benzimidazol-1-yl)phenyl)dimethylsilane (2) have been synthesized and determined by IR, 1H NMR, 13C NMR and mass spectroscopy. These compounds have high thermal stability and are fluorescent with emission in the region of violet to blue, which could be potentially applied as blue emitters in organic light-emitting diodes (OLEDs) display.
