We report the synthesis and the in depth electrochemical study of two novel electron accepting sulfonated perylene diimide pyrazolate ligands. Bridging the sulfone moieties of the perylene core unexpectedly affected the optical and electronic properties as evidenced by spectroelectrochemical investigation. Notably, we achieved a significant lowering of the LUMO level to −4.83 eV, ranking the ligand among the best electron acceptors via a straightforward synthetic procedure. These ligands can be foreseen for the development of n-type functional materials.

新型磺化苝二亚胺吡唑盐配体:通往 n 型氧化还原活性杂化材料的简单途径

我们报告了两种新型电子接受磺化苝二亚胺吡唑盐配体的合成和深入电化学研究。正如光谱电化学研究所证明的那样,桥接苝核心的砜部分出乎意料地影响了光学和电子特性。值得注意的是,我们实现了 LUMO 水平的显着降低至-4.83 eV,通过简单的合成程序将配体列为最佳电子受体。可以预见这些配体将用于开发 n 型功能材料。
