Abstract

The invention belongs to the technical field of organic electroluminescent materials, and in particular relates to a nitrogen-containing seven-membered ring compound of Sanyaphenanthrene and its preparation method and application. The compound has a structure shown in formula (F). This type of compound is centered on a nitrogen-containing seven-membered ring, and it is difficult to form a large π-π conjugated system, so that the electron migration and charge transfer tendency of the whole system are balanced to a certain extent. Moreover, the glass transition temperature of this type of compound is high, and it is easy to form a uniform thin film, so that the material has good thermal stability and high luminous efficiency.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescent materials, and in particular relates to a nitrogen-containing seven-membered ring compound of Sanyaphenanthrene and its preparation method and application. Background technique [0002] Organic light-emitting diodes (OLEDs) based on small molecules or polymers have attracted much attention due to their potential applications in full-color, flat-panel displays, and lighting since the pioneering work of Tang et al. Diodes (OLEDs), as a brand-new display technology, have unparalleled advantages in various performances of existing display technologies, such as all-solid-state, self-luminous, high brightness, high resolution, wide viewing angle (above 170 degrees), Fast response, thin thickness, small size, light weight, flexible substrate, low-voltage DC drive (3-10V), low power consumption, wide operating temperature range, etc., make it widely used in the market, such as lighting ...
