Synthesis of the elusive N‐annulated perylene diimide dimer with pyrrolic N–H bonds is reported. The parent tPDI₂NH dimer can be used as an electron transport material in OFETs or non‐fullerene acceptor on OSCs. The N–H bonds can easily be functionalized to incorporate alkyl side chains or cleavable “tBOC” groups. The acidic N–H bonds can be deprotonated to give drastic color changes in solution or as thin films.

带有吡咯式N–H键和N-官能化衍生物的Per二酰亚胺二聚体的合成，用于有机场效应晶体管和有机太阳能电池

报道了具有吡咯NH键的难以捉摸的N-环per二酰亚胺二聚体的合成。母体tPDI ₂ NH二聚体可用作OFET中的电子传输材料或OSC上的非富勒烯受体。N–H键很容易被官能化以结合烷基侧链或可裂解的“ tBOC”基团。酸性的N–H键可以去质子化，从而在溶液或薄膜中产生剧烈的颜色变化。
