摘要:
利用不同种类的烷基链作为合适间隔基团,设计并合成了 3 个咔唑类衍生物(PhOCz-C3,PhOCzC4和PhOCz-C5)。在咔唑基团上引入芳基酮单元,以增强分子内电荷转移和自旋轨道耦合效应。PhOCzC5具有室温磷光特性,其在晶体中的排列方式呈鱼骨状,其分子间相互作用较强,包括C-H?O/ C-H?N氢键和 C-H?π 相互作用。长程有序的聚集方式可以锁定相邻的分子,以增强晶体整体的刚性,这有利于室温磷光特性的产生。结果表明:通过整合多种分子设计策略获得室温磷光化合物,有助于深入理解有机化合物的堆积形式与光电性能之间的关系,也为刺激响应型材料的设计提供新的思路。
Abstract:
Three carbazole derivatives, namely PhOCz-C3, PhOCz-C4 and PhOCz-C5, have been designed and synthesized, using different types of alkyl chains as suitable spacer groups. The aryl ketone unit was introduced onto the carbazole group to enhance the intramolecular charge transfer and spin-orbit coupling effect. PhOCz-C5 exhibits room-temperature phosphorescence property, and its arrangement in the crystal is fishbone-shaped, with strong intermolecular interactions, including C-H?O / C-H?N hydrogen bonds and C-H?π interactions. The long-range ordered aggregation can lock adjacent molecules, enhancing the rigidity of the entire crystal, which is beneficial for the generation of room-temperature phosphorescence characteristics. The results show that integrating multiple molecular design strategies to obtain room-temperature phosphorescent compounds can help us deeply understand the relationship between the stacking form and the photoelectric properties of organic compounds, and also provide new ideas for the design of stimulus-responsive materials.
