Recently, by mastering either top-down or bottom-up approaches, tailor-made macromolecular nano-objects with semiconducting properties have been fabricated. These engineered nanostructures for organic electronics are based on conjugated systems predominantly made up of sp²-hybridized carbon, such as graphene nanoribbons. Here, we describe developments in a selection of these nanofabrication techniques, which include graphene carving, stimulus-induced synthesis of conjugated polymers and surface-assisted synthesis. We also assess their potential to reproduce chemically and spatially precise molecular arrangements, that is, molecular blueprints. In a broad context, the engineering of a molecular blueprint represents the fabrication of an integrated all-organic macromolecular electronic circuit. In this Perspective, we suggest chemical routes, as well as convergent on-surface synthesis and microfabrication approaches, for the ultimate goal of bringing the field closer to technology.
最近，通过掌握自上而下或自下而上的方法，已经制备出具有半导体性质的定制大分子纳米物体。这些用于有机电子学的工程纳米结构主要基于由 sp² 杂化碳组成的共轭体系，例如石墨烯纳米带。在这里，我们描述了一系列这些纳米制造技术的发展，包括石墨烯雕刻、刺激诱导的共轭聚合物合成和表面辅助合成。我们还评估了它们在复制化学和空间精确分子排列方面的潜力，即分子蓝图。从更广泛的角度来看，分子蓝图的工程代表了集成全有机大分子电子电路的制造。在本观点中，我们提出了化学途径，以及汇聚的表面合成和微制造方法，以最终实现将该领域推向技术的目标。
