[0245] Preparation Example 1. Preparation of Compound 1

[0246] (1) Preparation of compound 1-b

[0247]

[0248] After dissolving 1-a (5.29 g, 6 mmol) in 150 mL of chloroform, N-bromosuccinimide (1.28 g, 7.2 mmol) was injected thereto at room temperature, and the resulting mixture was stirred for 48 hours. After the reaction, the reactant was added to 250 mL of water, and extracted with dichloromethane. After this time, the remaining water was removed over magnesium sulfate, and the solvent was removed under reduced pressure. The remaining product was purified with a silica gel column (eluent: hexane:dichloromethane=2:1) ​​to obtain black powder 1-b. (yield: 71%)

[0249] figure 2 is a graph showing the MS spectrum of compound 1-b.

[0250] (2) Preparation of compound 1-c

[0251]

[0252] 1-b (4.092 g, 4.26 mmol) and 2-aldehyde-thiophene borate (0.935 g, 6 mmol) were dissolved in 200 mL of tetrahydrofuran and 50 mL of 2M potassium carbonate, to which was added ...

preparation example 2

[0270] Preparation Example 2. Preparation of Compound 2

[0271]

[0272] Prepared in the same manner as the preparation of Compound 1 above, except that 40 mL of CHCl was used in the preparation of Compound 1 3 Compound B (1.09 g, 0.4 mmol) and DiCN-rhodanine (0.773 g, 3 mmol) in . (yield: 71%)

Abstract

The present specification relates to a heterocyclic compound and an organic solar cell comprising the same.

Description

technical field [0001] This specification claims priority and benefit from Korean Patent Application No. 10-2015-0055432 filed with the Korean Intellectual Property Office on Apr. 20, 2015, the entire contents of which are incorporated herein by reference. [0002] This specification relates to heterocyclic compounds and organic solar cells comprising them. Background technique [0003] A solar cell is a device that directly converts solar energy into electrical energy by applying the photovoltaic effect. According to the material constituting the thin film, solar cells can be classified into inorganic solar cells and organic solar cells. A typical solar cell is made by doping crystalline silicon (Si), which is an inorganic semiconductor, through a p-n junction. Electrons and holes generated by absorbing light diffuse to a p-n junction, and move to an electrode while being accelerated by an electric field. The power conversion efficiency in this process is defined as the ...
