DPP Organic Blue Dyes featuring a Diketopyrrolopyrrole Preparation Method Thereof and Dye-sensitized Solar Cells Comprising the Same

摘要

The present invention is It provides a method for producing the organic blue dye based on diketopyrrolopyrrole (DPP) represented by the following formula (1) and a dye-sensitized solar cell including the same. D-π-A-π'-A' Formula (1) In the above formula (1), D(donor) is (R 1 )(R 2 )NC 6 H 5 -, wherein R 1 and R 2 are each independently hydrogen, a halogen atom, substituted or unsubstituted C1-C20 alkyl, substituted or unsubstituted C1 -C20 alkoxy, substituted or unsubstituted C4-C10 aryl, or substituted or unsubstituted C3-C10 heteroaryl; π (π spacer) is -π 1 -π 2 -, wherein π 1 and π 2 are each independently a substituted or unsubstituted C2-C6 alkene, C2 alkyne, substituted or unsubstituted C4-C10 aryl, or substituted or unsubstituted C3-C10 heteroaryl; A is wherein R 3 and R 4 are each independently hydrogen, a halogen atom, substituted or unsubstituted C1-C20 alkyl, or substituted or unsubstituted C1-C20 alkoxy; π'(π' spacer) is -π' 1 -π' 2 -, wherein π' 1 and π' 2 are each independently a substituted or unsubstituted C2-C6 alkene, C2 alkyne, substituted or unsubstituted C4- C10 aryl, or substituted or unsubstituted C3-C10 heteroaryl; A' is an anchoring group; the substituent is at least one selected from the group consisting of a halogen atom, hydroxy, C1-C10 alkyl, and C1-C10 alkoxy; and The hetero atom may be one or more selected from the group consisting of N, O and S. wherein R 1 and R 2 are each independently substituted or unsubstituted C1-C5 alkyl, substituted or unsubstituted C6 aryl, or substituted or unsubstituted C4-C5 heteroaryl; Here, the substituent may be at least one selected from the group consisting of C1-C5 alkyl, and C1-C5 alkoxy. π 1 , π 2 , π′ 1 , and π′ 2 are each independently C2 alkyne, substituted or unsubstituted C6 aryl, or substituted or unsubstituted C4-C5 heteroaryl; wherein the substituent is at least one selected from the group consisting of C1-C2 alkyl and C1-C2 alkoxy; And the hetero atom may be at least one selected from the group consisting of N, O and S.
