近日，北京大学化学与分子工程学院教授裴坚及其课题组揭示BN包埋的二烯丙基二酰亚胺的模块化方法。该研究于2025年3月17日发表于国际一流学术期刊《德国应用化学》杂志上。

这项工作提出了杂原子嵌入的涤纶二亚胺（TDIs）的第一个例子，它是由BN嵌入的亚胺构建块以模块化的方式合成的。通过控制BN单元的数量和取向，实现了对BN-TDIs偶极矩的操纵，从而将BN-TDIs的荧光扩展到近红外区域。通过单晶X射线衍射确定了BN-TDIs的结构。与TDI相比，BN-TDIs的晶体结构中羰基-π相互作用更强，这可以用于构建超分子结构。制备了基于BN-TDIs的有机薄膜晶体管。BN-TDI-S表现出比TDI更高的电子迁移率，表明BN-TDIs具有作为n型有机半导体的潜力。

Abstract: This work presents the first example of heteroatoms embedded terrylene diimides (TDIs), which were synthesized from the BN-embedded imide building block in a modular manner. Through the control of the amount and orientations of the BN unit(s), the manipulation of dipole moments of the obtained BN-embedded terrylene diimides (BN-TDIs) was achieved, which in turns extended the fluorescence of BN-TDIs to near infrared region. The structures of BN-TDIs were established via single crystal X-ray diffractions. Stronger carbonyl-π interactions were observed for BN-TDIs in their crystal structures compared with that of TDI, which could be utilized in the construction of supramolecular architectures. The organic thin film transistors based on BN-TDIs were also fabricated. BN-TDI-S showcased higher electron mobilities than that of TDI, indicating the potential of BN-TDIs as promising n-type organic semiconductors.
