Abstract

The invention relates to a polymer electroluminescent material containing an amide iridium metal complex and a preparation method thereof, which belong to the synthetic material and electroluminescent material technology field. The invention discloses the polymer electroluminescent material containing the amide iridium metal complex, the metal complex of the polymer adopts a metal complex containing a 2-phenylpyridine structure, the molecular structural formula is (L<2>)2Ir(MA), wherein the L<2> signifies bidentateligand containing the 2-phenylpyridine, and the MA signifies bidentateligand containing amide structure and double bonds. The synthesized polymer is divided into two types, one is the homopolymer Poly (L<2>)2Ir(MA), of the metal complex, or the other is the homopolymer Poly VK-(L<2>)2Ir(MA) of the metal complex and the N-vinyl carbazole (N-VK). All the polymers containing the iridium metal complex synthesized in the invention have higher luminescence performance in the solution at room temperature, and can be used as the functional material in organic electroluminescent devices.

Description

technical field

[0001] The polymer electroluminescent material containing amide-type iridium metal complex and its preparation relate to the electroluminescent material containing the polymer of amide-type Ir(III) metal complex which can be used in the field of electroluminescence. The invention belongs to the technical field of synthetic materials and electroluminescent materials. Background technique

[0002] Organic luminescence (electroluminescence, EL) refers to the phenomenon that luminescent materials are excited by current and electric field under the action of an electric field to emit light. It is a luminescent process that directly converts electrical energy into light energy. The research on organic electroluminescent devices (OEL), that is, organic light-emitting diodes (OLEDs), began in the 1950s. By 1987, Eastern Kodak Company Tang et al. adopted an organic small molecule material with high fluorescence efficiency, electron transport properties and vacuum coa...
