A bis-phenanthroimidazolyl compound having a following formula is disclosed.
Where A1 and A2 comprise identical or different aromatic rings, A3 comprises a polyaromatic hydrocarbon or at least two aromatic groups, and each carbon in A1 to A3 and phenanthrol groups is independently substituted or non-substituted. The bis-phenanthroimidazolyl compound exhibits relatively better thermal properties with higher glass-transition temperature and efficient blue emission. The bis-phenanthroimidazolyl compound may function as a host emitter or charge-transporter. An electroluminescent device is also disclosed.
