Embodiment approach
[0017] Embodiments of the present invention will be described in detail below.
[0018] The production method of the present invention is characterized in that it is a method of producing a conjugated polymer by Suzuki coupling, wherein the conjugated polymer is produced by irradiating microwaves.
[0019] In the present invention, the so-called "conjugated polymer" refers to a fully conjugated polymer, in other words, a polymer that is conjugated throughout the entire length of its polymer chain, or a partially conjugated polymer, in other words, at the same time Any of polymers containing conjugated moieties and non-conjugated moieties.
[0020] The monomer used in the method for producing a conjugated polymer of the present invention is not particularly limited, and any monomer can be used as long as the conjugated polymer can be obtained by the Suzuki coupling reaction.
[0021] The monomer used in the production method of the conjugated polymer of the present invention m...

[0060] Polymer Synthesis (1)
[0061] The reaction was carried out using a dedicated polytetrafluoroethylene reaction vessel. The solvent is first used with nitrogen gas for more than 30 minutes, and then used after deoxygenation treatment in the solvent. Add 2,7-dibromo-9,9-dioctylfluorene (P9) (0.4mmol), 9,9-dioctylfluorene diboronic acid ester (B13) (0.4mmol) in the reaction vessel, and then In a glove box (glove box) under a nitrogen atmosphere, add 3vol% trioctylmethylammonium chloride in toluene or anisole solution (8ml, refer to Table 1), 8mM Pd (PPh 3 ) 4Toluene or anisole solution (see Table 1) to obtain a mixture. After the mixture was stirred to dissolve the monomers, a 2M aqueous base solution (5.3 ml, see Table 1) was added. The reaction vessel was placed in a microwave reaction device, and while stirring, under the conditions shown in Table 2, the Suzuki coupling reaction was carried out under the irradiation of microwaves. In reference examples (reference) ...

[0072] Polymer Synthesis (2)
[0073] The reaction was carried out using a dedicated polytetrafluoroethylene reaction vessel. The solvent is first used for more than 30 minutes with nitrogen gas to deoxidize the solvent before use. Add 4,7-dibromo-2,1,3-benzothiazole (R5) (0.08mmol), 4,4'-dibromotriphenylamine (R12) (0.32mmol), 9, The diboronic acid ester (B13) (0.4mmol) of 9-dioctyl fluorene, and then in the glove box under nitrogen atmosphere, add the toluene of 3vol% trioctylmethylammonium chloride or anisole solution (8ml, refer to Table 4), 8mM Pd(PPh 3 ) 4 Toluene or anisole solution (see Table 4) to obtain a mixture. After stirring the mixture to dissolve the monomers, add 2M K 2 CO 3 Aqueous solution (5.3ml). The reaction vessel was placed in a microwave reaction device, and while stirring, according to the conditions shown in Table 5, the Suzuki coupling reaction was carried out under the irradiation of microwaves. After the reaction was completed, the reactio...
