- Novel dithieno silicon heterocyclic pentadiene organic solar cell acceptor material, and preparation method, and applications thereof
-
The invention provides a novel dithieno silicon heterocyclic pentadiene organic solar cell acceptor material, and a preparation method and applications thereof. The novel dithieno silicon heterocyclicpentadiene organic solar cell acceptor material is a linear-type non-fullerene organic solar cell acceptor material with an A-D-A structure, and the structure general formula is disclosed in the invention, wherein m is used for representing a natural number selected from 2 or 3; R1 and R2 are used for representing alkyl straight chains or straight chains with a carbon atom number ranging from 1 to 20; and B1 and B2 are used for representing electron withdrawing terminals. The novel dithieno silicon heterocyclic pentadiene organic solar cell acceptor material is capable of solving problems inthe prior art that conventional non-fullerene small molecular acceptor material is simple in molecular structure, and low in molecular weight; the preparation method is simple; the synthesis raw materials are cheap and easily available; and it is beneficial for early commercialization applications of organic solar cells.

- organic semiconductor compound, manufacturing method thereof, and organic electronic device that contains it
-
The present invention relates to an organic semiconductor compound, a method for manufacturing the same, and an organic electronic device comprising the same and, more specifically, to an organic semiconductor compound including quinoxaline, a method for manufacturing the same, and an organic electronic device comprising the same. In addition, by having a low band gap by synthesizing and copolymerizing a thiophene derivative containing sulfur (S) with a quinoxaline-based compound, the organic electronic device comprising the same has a higher efficiency with an innovative combination with a fullerene derivative, which is a photoactive layer, with the organic semiconductor compound of the present invention. The organic semiconductor compound of the present invention has high thermal stability and high solubility and the organic electronic device comprising the same has excellent electric characteristics, thereby can be valuably used as a n-type material of the organic electronic device, especially an organic solar cell or an organic thin film transistor.
