| Abstract: | A series of organic fluorescent materials based on pyrene-imidazole was designed and synthesized by one-pot reactions.The compounds were thoroughly characterized by 1H NMR and 13C NMR spectroscopy, mass spectroscopy and elemental analysis and corresponded well with their expected structures.The conjugation degree, spatial structure, the highest occupied molecular orbital(HOMO) and the lowest unoccupied molecular orbital(LUMO) energy levels are fine-tuned by the various substituents at C1 position of imidazole.They also increase the thermal stabilities of these pyrene-imidazole derivatives.These materials show potential applications in organic light-emitting diodes. |
