Abstract

The invention discloses an organic porous polymer which is shown as the following general molecular formula and constructed by taking pyrene and 9,9-dioctylfluorene as monomers: (the general molecularformula is shown in the specification). The organic porous polymer can be used as an organic electroluminescence material for preparing a white light-emitting organic electroluminescence material bybeing doped with other micromolecular organic electroluminescence materials with complementary emitting colors. The doped other micromolecular organic electroluminescence materials can enter holes ofthe organic porous polymer, so as to keep the single-phase property of the polymer, avoid the phase separation and interface degradation phenomena caused by doping, and keep the emitting color stable.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescent materials, and relates to a polymer organic electroluminescent material with a porous structure, in particular to a porous structure polymerized with pyrene and 9,9-dioctylfluorene as building monomers. An organic electroluminescent material, and a preparation method of the organic electroluminescent material. Background technique [0002] "Energy saving and low consumption" has become the theme of social development. Organic light-emitting devices (Organic light-emitting devices, OLED) have the advantages of all solid state, high brightness, self-illumination, wide viewing angle, thin thickness, etc., and are widely recognized by researchers. focus on. Among them, organic electroluminescent polymer materials and devices have the characteristics of simple process and easy realization of large-screen display and flexible display, which have aroused great interest of researchers,...
