The invention discloses a trans-A2B2 porphyrin derivative, and a preparation method and an application thereof. The preparation method comprises the following steps: carrying out a reaction on 4-alkoxybenzaldehyde and pyrrole under the catalysis of trifluoroacetic acid to synthesize 5-substituted dipyrrylmethane; carrying out a cyclization reaction on the obtained 5-substituted dipyrrylmethane and 5-bromo-2-thiophenecarboxaldehyde under the action of trifluoroacetic acid and dichlorodicyan benzoquinone to form a porphyrin ring main body; connecting the thiophene alpha position of the porphyrin ring with a boronic acid pinacol ester group through using a Suzuki coupling reaction to modify the porphyrin ring; and carrying out the Suzuki coupling reaction on bromodicyanovinyl oligothiophene prepared in the early stage and the modified porphyrin ring under the catalysis action of palladium to obtain the final product. The trans-A2B2 porphyrin derivative is hopeful to become a high-efficiency organic photovoltaic battery donor material due to the unique molecular structure and large conjugated system.
