Controlling molecular self-assembly of organic semiconductors is a key factor in enhancing the performance of organic electronics and optoelectronics. However, unlike various p-type organic semiconductors, it has proven elusive to control molecular self-assembly with about tens of nm dimensions using n-type organic semiconductors including perylene diimide (PDI), which is the most promising alternative to fullerene derivatives, without using an additional synthetic method or additives, thus far. Here, we developed a simple self-assembling method for the hierarchical self-assembly of PDI crystals with nanometer-to-micrometer scale features using pristine PDI-C8 without using an additional synthetic method or additive. Interestingly, we observed crystalline and optical properties of self-assembled PDI crystals depending on their size and structural features. In addition, we fabricated p-n junctions composed of PDI and poly(3-hexylthiophene) (P3HT), where the p-n junctions had coassembled and blended nanomorphologies, and confirmed that coassembled nanomorphologies enabled more effective energy transfer than the blended nanomorphologies.

ylene二酰亚胺(PDI)晶体的分层自组装。
控制有机半导体的分子自组装是增强有机电子和光电性能的关键因素。但是,与各种p型有机半导体不同,事实证明,使用包括per二酰亚胺(PDI)在内的n型有机半导体控制富勒烯衍生物的最有希望的替代方法是,使用包括per二酰亚胺(PDI)在内的n型有机半导体来控制约数十纳米尺寸的分子自组装是难以实现的。到目前为止,使用其他合成方法或添加剂。在这里,我们开发了一种简单的自组装方法,该方法使用原始的PDI-C8进行具有纳米级至微米级特征的PDI晶体的分层自组装,而无需使用其他合成方法或添加剂。有趣的是 我们观察到了自组装PDI晶体的晶体和光学特性,具体取决于它们的大小和结构特征。此外,我们制造了由PDI和聚(3-己基噻吩)(P3HT)组成的pn结,其中pn结具有共组装和共混的纳米形态,并且证实了共组装的纳米形态比共混的纳米形态能实现更有效的能量转移。
