Cross-link polymer organic compound luminous material and their preparation

Abstract

The present invention interconnects polymer or luminescent organic compound material via crosslinking and forms interacting crosslinking bond, crossslinking segment, coordinate bond or hydrogen bond among molecules. The prepared luminescent material has stereo structure, planar structure and other structural form, and this raises or alters the luminescence efficiency, luminescence bright, luminescence life, luminescent device stability, luminescence wavelength, color purity, and luminescent device performance.

Description

1. Technical field [0001] The invention belongs to the field of materials, optical devices, optoelectronic devices or electronic devices, and particularly relates to polymer and organic compound light-emitting materials and their preparation process. 2. Background technology [0002] Existing photo-induced and electro-induced organic and polymer luminescent materials are polymers or organic molecules with conjugated structures, such as polyphenylene vinylene, polythiophene, 8-hydroxyquinoline and some organic dyes. The molecules that make up these luminescent materials are independent and not connected to each other, that is, the molecules are not connected or cross-linked by chemical bonds, chemical groups, molecular chains, and the like. There are a variety of preparation methods for these materials, but the prepared molecules are all one-dimensional linear structures or small molecules, that is, the molecules are not connected to each other. These materials all have vari...
