Red and green light emitting conjugated polymer and preparation method as well as application thereof
The invention discloses a red and green light emitting conjugated polymer. The conjugated polymer is a single-chain fluorene-based random copolymer composed of three unary compounds. The three unary compounds are 9,9-dialkyl fluorine, 2,1,3-benzthiadiazole and 4,7-bis(2'-thienyl)-2,1,3-benzthia...

| description | The invention discloses a red and green light emitting conjugated polymer. The conjugated polymer is a single-chain fluorene-based random copolymer composed of three unary compounds. The three unary compounds are 9,9-dialkyl fluorine, 2,1,3-benzthiadiazole and 4,7-bis(2'-thienyl)-2,1,3-benzthiadiazole, and the mol ratio thereof is 1-x-y:x:y, wherein, x is not less than 0.05 but not more than 0.45, and y is not less than 0.00001 but not more than 0.0005. In the conjugated polymer, light emitting units of different colors are copolymerized on a single molecular chain by covalent bonds to produce single chain multi-spectral emission. The conjugated polymer is characterized by simple synthesis and preparation and stable thin film morphology, thus achieving emission of white light with stable spectrum, which is of great significance to the application in the fields of back light sources and lighting. |
