Abstract

The invention discloses an osmium-containing conjugated polymer as well as a preparation method and application thereof. The osmium-containing conjugated polymer has a structural formula as shown in the specification. The osmium-containing conjugated polymer prepared by the preparation method disclosed by the invention is high in solubility, good in stability, relatively high in molar absorption coefficient and relatively good in electrochemical performance, and linking groups with different function orientations can be introduced, so that the osmium-containing conjugated polymer is functionalized. The preparation method provided by the invention has the advantages of simple and efficient polymerization route, mild reaction conditions, good functional group tolerance and good universality. The osmium-containing conjugated polymer can be widely applied to the fields of solar cells, light-emitting diodes, field effect transistors, chemical sensors, chemical switches and the like.

Description

technical field [0001] The invention belongs to the technical field of metal organic chemistry, and in particular relates to an osmium-containing conjugated polymer and a preparation method and application thereof. Background technique [0002] Conjugated polymers refer to a class of polymers with large conjugated delocalized π bonds. Its main feature is that electrons and energy can be transferred throughout the polymer backbone. Not only has excellent photoelectric properties, but also has good processing properties and mechanical properties (Chemical reviews 2007, 107(4), 1324-38.). Because of its applications in light-emitting diodes (J.Mater.Chem.C 2015,3(13),2974-3002), solar cells (Advanced materials 2014,26(7),1006-24.), chemical sensors (Nature communications 2014, 5,5404.) and other fields have attracted much attention. However, traditional organic conjugated polymer materials cannot meet the development needs of future energy chemistry. [0003] The introducti...
