Heteroaryl compound exhibiting luminescent ferroelectric and piezoelectric properties and electronic device containing the same

摘要

The present invention relates to a heteroaryl compound exhibiting luminescence, ferroelectricity and piezoelectricity, and an electronic device including the same. Since the heteroaryl compound may induce tautomerization by including a benzoimidazole group and/or a benzazaphosphole group having an asymmetric structure as a parent nucleus, excellent ferroelectricity and piezoelectricity may be implemented along with luminescence through this. In addition, since an electronic device having an organic layer including the compound can implement both luminescence, ferroelectricity and piezoelectricity, the luminous characteristics are easily controlled by controlling the AC power applied according to the polarity or size of the residual polarization generated in the organic layer. In addition to being possible, since it is not necessary to include a light-emitting material and a ferroelectric and/or piezoelectric material, respectively, there is an advantage of excellent workability and excellent durability.
