Embodiment 1

[0014] Example 1: Preparation of fluorine-containing conjugated polymers with the structure of Formula 1

[0015] 200.0 mg monomer M1, 158.78 mg M2, 45 mL THF, 15 mL toluene, 4 mL water, and 0.4 g NaHCO 3 In a 100ML slit-gate flask, add 3.6mg of Pd (PPh 3 ) 4 Before and after, the nitrogen gas was repeatedly filled and degassed, and then the system was stirred and refluxed for 72 hours under a nitrogen atmosphere. Then cool the system, add 10mg phenylboronic acid and 1.8mg Pd(PPh 3 ) 4 Raise the temperature and react for 4 hours, then cool down and add 100 μL of bromobenzene to raise the temperature and continue the reaction overnight to complete capping. After the system was cooled to room temperature, water and chlorobenzene were added; the organic layer was separated with a separatory funnel and washed three times with water. Then heat the organic phase to 100°C to dissolve part of the precipitated polymer, filter the organic phase and rotary evaporate the filtrate to...

Abstract

The invention discloses a preparation method for a novel fluorine-containing narrow band gap conjugated polymer material and applications. The structure of the fluorine-containing narrow band gap conjugated polymer is shown in the formula I, wherein n is an integer which is more than or equal to 4. At present, conjugated polymers with main chains with structures of alternate donors and acceptors are the focus of present research. Fluorine-containing organic conjugated polymers often have excellent thermostability, oxidation stability, corrosion resistance, hydrophobicity and lipophobicity fluoride substrates and electron density distribution overturn of fluorate aromatic rings. Some research on applications of fluorine substituted conjugated polymers in organic field effect transistors and organic luminescence diodes have been studied. But fluorine substituted materials are rare, especially as P type semiconductors, in applications of photovoltaic materials.

Description

technical field [0001] The invention belongs to the field of organic solar cell materials, and in particular relates to the preparation of a novel fluorine narrow band gap conjugated polymer material. As the world is facing an energy crisis, photoelectric conversion technology is considered to be one of the most important renewable energy sources. Among them, polymer solar cells have received extensive attention due to their advantages of low cost, light weight, and large-area preparation. One of the important factors to obtain high photoelectric conversion efficiency is to develop electron donor materials with excellent properties. At present, the highest conversion efficiency has reached 10%. Background technique [0002] Although the research on polymer solar cells has achieved remarkable results, there is still a big gap from the goal of "Double 10" (that is, 10% photoelectric conversion efficiency and 10-year service life), although the current highest photoelectric c...
