- Spiro[fluorene-9,9'-xanthene]-based small organic molecule hole transport material as well as preparation method and application thereof
-
The invention discloses an organic small molecule hole transport material based on spiro[fluorene-9,9'-xanthene]-based and a preparation method and application thereof, and the organic small moleculehole transport material takes spiro[fluorene-9,9'-xanthene] as a core, and has good amorphous form and excellent dissolving property; besides, different numbers of thiophene groups are added into sidechains, so that the material is endowed with more excellent physical and photoelectric properties through the characteristics of high electron density, excellent carrier transport capacity, controllable optical and electrochemical properties and the like; in addition, due to modification of a terminal alkyl chain, the dissolvability is improved, the film-forming property of the material is facilitated, and the material is easier to process; meanwhile, the synthesis is simple, raw materials are easy to obtain, and cost is low. The organic small molecule hole transport material is applied to anall-inorganic perovskite solar cell, and the cell efficiency of the organic small molecule hole transport material is higher than the original cell efficiency, which shows that the organic small molecule hole transport material has practical significance for improving the efficiency of the all-inorganic perovskite solar cell.
