Abstract

The invention discloses a method for assembling an ultra-thin ordered conductive polymer film at a liquid / air interface, which comprises the following steps: dissolving the conductive polymer in an oily solvent, the used oily solvent must be insoluble in water and have a low boiling point, and at the same time change the The selection of the solvent and the type and concentration of the dopant, through the interface induction, assemble an ultra-thin ordered conductive polymer film at the liquid / gas interface. Stablize. The preparation process of the present invention is simple, easy to operate, low on environmental factors, and does not require expensive and complicated experimental equipment. Practice has proved that this method can prepare ultra-thin ordered conductive polymer films. It has important theoretical and practical significance to further clarify the relationship between molecular orientation and stacking structure and charge transport and to develop high-performance organic electronic materials.

Description

technical field [0001] The invention relates to the technical field of organic electronic materials, in particular to a method for assembling an ultra-thin ordered conductive polymer film at a liquid / gas interface. Background technique [0002] Organic electronic devices have a series of excellent properties and show great application potential, and have attracted extensive attention from academia and industry at home and abroad in recent years. However, their disadvantages such as slow running speed, low work efficiency and short service life have also seriously hindered their further development. To fundamentally solve these problems and make organic electronic devices better for our use, it is necessary to further improve the performance of organic semiconductor materials and design more reasonable organic molecular structures. To achieve this goal, we must correctly understand the charge transport of organic semiconductor materials and organic electronic devices, which ...
