由于p-共轭生色团在有机电子学中作为活性组分的重要作用，将其超分子组装成具有良好结构的纳米结构已经引起了人们的广泛关注。电荷转移（CT）纳米结构，其中芳香族供体（D）和受体（A）分子交替排列，（混合堆叠）最近已经出现作为在这个方向的前景候选人，因为它们提供了固有的，均匀的掺杂有利于优异的导电性能。本观点强调了基于电荷转移（CT）的非共价相互作用的重要性，强调超分子设计原则，用于构建各种CT纳米结构。全文分为三个部分，主题是用于获得CT组件的交互类型。通过我们最近的一些结果，我们试图突出这个新生领域的潜在潜力。此外，我们还就这一领域的主要挑战提出了我们的看法，预计这将扩大这一主题的范围。
Supramolecular organization of p-conjugated chromophores into well defined nanostructures has gained much attention due to their promising role as active components in organic electronics. Charge-transfer (CT) nanostructures, in which aromatic donor (D) and acceptor (A) molecules are alternately arranged, (mixed stack) have emerged recently as prospective candidates in this direction, because they provide inherent, uniform doping conducive for excellent conducting properties. The present perspective highlights the importance of charge transfer (CT) based non-covalent interactions, with emphasis on supramolecular design principles, for construction of various CT nano-architectures. The whole article is divided into three parts themed on the type of interactions used for obtaining CT assemblies. Through some of our recent results, we have attempted to highlight the latent potential of this nascent field. Furthermore, we have presented our perspectives on the major challenges in this field which is expected to broaden the scope of this subject.
