Large conjugate twisted molecule and electroluminescent device

The invention discloses a large conjugate twisted molecule and an electroluminescent device, which are characterized in that a plane structure is introduced into a twisted spiral carbon molecule to adjust the twisting posture of the molecule, so that the microcosmic transformation of the molecule is realized, the conjugation of the molecule is improved, the rigidity of the molecule is increased, and the symmetry of the molecule is reduced; the driving voltage of the electroluminescent device prepared from the large conjugate twisted molecule is reduced, the luminance is obviously improved, the efficiency of the whole device is effectively improved, and the service life of the device is longer than that of a traditional material device. 本发明公开了一种大共轭扭曲分子及电致发光器件，通过向扭曲的螺碳分子内引入一个平面结构来调整分子扭曲姿态，从而实现对分子的微观改造，提升分子的共轭，同时增加分子的刚性，降低分子的对称性；本发明大共轭扭曲分子制成的电致发光器件驱动电压降低，发光亮度明显改善，整体器件效率得到有效提升，且器件寿命比传统的材料器件寿命更优。
