Compounds using fluorene as core, preparation method of compounds and application of compounds in organic light emission diode device

The invention relates to organic compounds using fluorene as a core, a preparation method of the compounds and an application of the compounds in an organic light emission diode (OLED) device. The compounds have a following structure: the fluorene is connected with a dibenzo five-membered ring and ring structure through a carbon-carbon bond, the carbon-carbon bond connection not only improves the chemical stability of the material, but also avoids exposure of active positions of a branched chain group, and the whole molecule is a larger rigid structure and has a higher triplet state energy level (T1); the compounds have large steric hindrance, are not easy to rotate, and have a more stable stereoscopic space structure, so that the compounds have a higher glass transition temperature and molecular thermal stability; in addition, HOMO and LUMO distribution positions of the compounds are separated from each other, so that the compounds have suitable HOMO and LUMO energy levels; therefore, the compounds can effectively improve the luminous efficiency and the service life of the device after being applied to the OLED device.

Organic xanthene compound and application thereof

The invention relates to an organic xanthene compound and application thereof to an OLED (Organic Light Emitting Diode) device. The structure of the compound is that xanthenes is connected with a carbazolocyclic structure through carbon-carbon bonds; due to carbon-carbon bond connection, the chemical stability of the material is improved, exposure of active positions of branched chain groups is avoided, and the whole molecule is of a great rigid structure and has high triplet state energy level (T1); moreover, the compound is high in steric hindrance, difficult to rotate and more stable in three-dimensional space structure, so the compound has high glass transition temperature and molecular thermal stability.
