| titleOfInvention | A kind of undoped organic small molecule hole transport material and its preparation method and application |
| abstract | The invention provides an undoped organic small molecule hole transport material, a preparation method and application thereof, and relates to the technical field of optoelectronic materials. The said undoped organic small molecule hole transport material uses benzodithiophene substituted by benzene ring as the central core, thiophene dithienothirole as π bridge, and rhodamine as the end group, which is added on the side chain of the central core. The benzene ring improves the conjugation of the molecule and is conducive to the formation of an intermolecular π-π stacking structure. The thiophenebithienosilole contains a longer C-Si bond, which reduces steric hindrance and further promotes the intermolecular π-π stacking structure. π stacking, resulting in a more ordered orientation. The non-doped organic small molecule hole transport material of the present invention has strong hole ability and strong ability to absorb light in the green wavelength range, and can significantly improve hole mobility, and is applied to perovskite High photoelectric conversion efficiency and strong stability can be obtained in solar cells. |
