Reactive vapor deposition (RVD) allows researchers to coat a diverse set of textiles with robust films of conjugated macromolecules and build conformally-integrated nanostructured electronics on textiles. However, the number of precursors amenable to RVD are limited, which in turn limits the variety of device architectures and optoelectronic functions that can be integrated with textile substrates. Here, we develop a dehydrogenative coupling reaction that can be used to create uniform, conformal and patternable polycyclic aromatic hydrocarbon (PAH) coatings on textiles using RVD protocols. PAHs possess large absorption coefficients, tunable band edges, high charge carrier mobilities and ambipolarity, meaning that a number of photonic and optoelectronic devices can be elaborated from the coatings reported here. We discuss, in particular, a fluoranthene/perifluoranthene composite PAH coating created using RVD, which exhibits strong light absorption over a large wavelength range and accompanying intermolecular energy transfer, qualifying it as a competitive photoactive material for conformally integrated, textile-based solar energy harvesters.

反应性气相沉积（RVD）使研究人员可以用坚固的共轭大分子薄膜覆盖多种纺织品，并在纺织品上构建共形集成的纳米结构电子器件。但是，适用于RVD的前驱物数量有限，进而限制了可与纺织品基材集成的设备架构和光电功能的多样性。在这里，我们开发了一种脱氢偶联反应，该反应可用于使用RVD协议在纺织品上形成均匀，保形和可图案化的多环芳烃（PAH）涂层。多环芳烃具有较大的吸收系数，可调谐的能带边缘，高的载流子迁移率和双极性，这意味着可以从此处报道的涂层中精制出许多光子和光电器件。我们特别讨论
