Preparation method and application of diketopyrrolopyrrole derivative

The invention discloses a preparation method and an application of a diketopyrrolopyrrole derivative. The invention relates to the technical field of diketopyrrolopyrrole catalysts. The preparation method comprises the following steps: adding a cyano heterocyclic compound into a sodium tert-amyl alcohol solution, heating the solution to 110-115 DEG C, dropwise adding a tert-amyl alcohol solution of diethyl succinate, performing reaction, and filtering, washing and drying the reaction solution after the reaction is finished to obtain the diketopyrrolopyrrole derivative. The invention also discloses an application of the diketopyrrolopyrrole derivative in photo-catalytic polar monomer polymerization reaction. The diketopyrrolopyrrole derivative can be used as a catalyst for photo-catalytic polar monomer polymerization reaction, so that the polymerization reaction can be carried out under a visible light condition, and the reaction can be carried out only by adding an initiator, a catalyst and a monomer subjected to the polymerization reaction without adding a reducing agent and other assistants in the polymerization reaction.

Synthesis of diketopyrrolopyrrole (DPP) derivatives comprising bithiophene moieties

Herein we disclose an easily applicable method for the synthesis of diketopyrrolopyrrole (DPP) derivatives comprising bithiophene moieties, with different substituents on the nitrogen atoms (Me, n-octyl, 3,5-di-tert-butylbenzyl, Boc) and on the thiophene rings (C6H13, C12H25), in good yields and purities. A comparison is made between the previously described method from literature and our more efficient approach regarding number of steps, overall yields and ease of synthesis and purification.
