Abstract[English]
The present invention aims to provide a pyrrolyl-based carbazole bisphosphonate polymer, a synthesis method therefor, and the use thereof. In the polymer, a conjugated structure is formed by linking two carbazole molecules via a pyrrole ring, and therefore the carrier transport efficiency when the material is applied to hole transport layers is ensured, the dipole moment of the molecule and the properties of an interface are well regulated, and the wettability and coverage effect with substrates are improved. Battery structures prepared by using the material have higher photoelectric conversion efficiency and stability.[French]
La présente invention vise à fournir un polymère de carbazole bisphosphonate à base de pyrrolyle, son procédé de synthèse et son utilisation. Dans le polymère, une structure conjuguée est formée par liaison de deux molécules de carbazole par l'intermédiaire d'un cycle pyrrole, et par conséquent l'efficacité de transport des porteurs lorsque le matériau est appliqué à des couches de transport de trous est assurée, le moment dipolaire de la molécule et les propriétés d'une interface sont bien régulés, et l'effet de mouillabilité et de couverture avec des substrats sont améliorés. Les structures de batterie préparées à l'aide du matériau ont une efficacité de conversion photoélectrique et une stabilité supérieures.[Chinese]
