Three new deep blue light emitters,bearing quinoxaline with different substituents(biphenyl/pyrene)at the 1-or 2-position,were synthesized by a Pd-catalysed coupling reaction in high yields,and were fully characterized by1H/13C NMR spectroscopy,single crystal X-ray diffraction,and high-resolution mass spectrometry(HRMS).
