Preparation method and application of bifurcated halogenated alkyl chain compounds

The invention discloses a preparation method and an application of bifurcated halogenated alkyl chain compounds. The method comprises the following steps: reacting bromoalkane with dimethyl malonate to obtain single-branch dimethyl malonate; reacting bromoalkane with the obtained single-branch dimethyl malonate to obtain two-branch dimethyl malonate; carrying out selective hydrolysis decarboxylation on the two-branch dimethyl malonate to obtain a hydrolysate; reducing the hydrolysate to obtain primary alcohol; carrying out a bromination reaction on the primary alcohol to obtain a brominated product; reacting the brominated product with ethylene oxide to obtain carbon chain-extended primary alcohol compounds; and carrying out a halogenation reaction on the carbon chain-extended primary alcohol compounds to obtain the bifurcated halogenated alkyl chain compounds with R being a corresponding halogen atom. The method has the advantages of low cost, high yield, simplicity in operation, andeasiness in realization of industrialization. Alkyl chains with different bifurcated lengths are introduced to an organic conjugated polymer, so the pi-pi piling distance between polymers is effectively reduced, the mobility of the polymer is improved.
