[0103] Preparation of Segmented Conjugated Polymers

[0104] The segmented conjugated polymer can be prepared by conventional methods in the art, such as by the following method:

[0105] (1) preparing a polymerized monomer, characterized in that the polymerized monomer has a conjugated segment and a non-conjugated segment located at one or both ends of the conjugated segment and connected to the conjugated segment, and the The end of the non-conjugated segment has a functional group (such as hydroxyl, amine, aldehyde, carboxyl, isocyanate, azide, halo, alkenyl or alkynyl, etc.) for polymerization to form a covalent bond ); wherein, the conjugated segment is a fully conjugated structure;

[0106] (2) Polymerization is carried out using the polymerizable monomer, thereby forming the polymer of the present invention.

[0107] Wherein, the reaction may be (but not limited to): urethanization reaction, esterification reaction, amidation reaction, imidization condensation reactio...
