specific Embodiment approach 3

[0025] Specific embodiment three: The preparation method of the DPP block polymer containing phenyltriphenylamine group in this embodiment is carried out according to the following steps:

[0026] 1. Synthesis of 3,6-bis(thiophen-2-yl)-2,5-bis(8-(tributylstannyl)octyl)pyrrolo[3,4-c]pyrrole-1,4(2H, 5H)-Dione: ①. Mix tert-amyl alcohol and sodium, add 2-cyanothiophene and dimethyl succinate to it, and pass N 2 For protection, after reacting at a temperature of 90~120℃ for 18~28h, the reaction temperature is lowered from 90~120℃ to 60~80℃, and then glacial acetic acid is added dropwise until a solid precipitates and the reaction solution is viscous. Add methanol and water for dilution, then cool to room temperature under stirring conditions, first wash with water 3 to 5 times and then wash with methanol 3 to 5 times to obtain a dark red solid, which is DPP; ②, the DPP obtained in step ①, Potassium tert-butoxide mixed with anhydrous DMF, and pass N 2 For protection, after reacting at ...

Abstract

The invention provides a DPP (Dipentyl Phthalate) block polymer containing a phenyl triphenylamine group as well as a preparation method and application thereof, and relates to the DPP block polymer containing the phenyl triphenylamine group as well as the preparation method and the application thereof, aiming at solving the problems that the solubility of a DPP type compound in an organic solventis low and the DPP type compound is difficultly processed into a film. The method comprises the following steps: 1, synthesizing 3,6-di(thiophene-2-yl)-2,5-bis(8-(tributyltinalkyl)octyl)pyrrolo[3,4-c]pyrrole-1,4-(2H,5H)-diketone; and 2, synthesizing the DPP block polymer containing the phenyl triphenylamine group. The material is applied to a photoelectric material and is used for detecting an electrochromic material, a fluorescent sensing material, a hole transport material, an anti-counterfeiting material, a camouflage material and an explosive substance and preparing a memory performance component.

Description

Technical field [0001] The invention relates to a DPP block polymer containing a phenyl triphenylamine group, its preparation method and application. Background technique [0002] DPP contains two mutually conjugated lactam groups, has strong electron withdrawing ability, and is a typical electron-deficient body. The two amides in the molecular structure can also be grafted with alkyl chains to improve their solubility in solution and adjust their assembly behavior. DPP has very strong luminescence properties in solution; it can absorb light in the visible region of the solar spectrum. With its chemical stability and easy synthesis and modification characteristics, it is a typical N-type molecular building unit. DPP has very broad application prospects in luminescent materials and solar cells. Because of its unique propeller-like structure, the triarylamine molecule has excellent heat resistance, light conductivity and hole transport properties. It is a typical P-type molecular...
