Via one-step copper catalyzed procedures it was possible to synthesize 2,5,8,11-tetrabromo, tetrachloro, and tetracyano derivatives of perylenediimides. Characterization of optical and electrochemical properties of these materials proves substantial enhancement of the electron affinity, with a LUMO level as low as -4.4 eV in the case of the tetracyano perylenediimide.
通过一步铜催化反应，可以合成并表征苝二酰亚胺的 2,5,8,11-四溴、四氯和四氰衍生物。这些材料的光电性能研究表明其电子亲和力显著增强，其中四氰基取代的苝二酰亚胺的最低未占据分子轨道（LUMO）能级低至-4.4 eV。
