反应气相沉积 (RVD) 使研究人员能够在多种纺织品上涂覆坚固的共轭大分子薄膜,并在纺织品上构建共形集成的纳米结构电子器件。然而,适合 RVD 的前驱体数量有限,这反过来又限制了可与纺织品基材集成的器件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,可用于使用 RVD 协议在纺织品上创建均匀、保形且可图案化的多环芳烃 (PAH) 涂层。 PAH 具有大的吸收系数、可调的能带边缘、高载流子迁移率和双极性,这意味着可以用本文报道的涂层来制作许多光子和光电器件。我们特别讨论了使用 RVD 创建的荧蒽/全荧蒽复合 PAH 涂层,该涂层在大波长范围内表现出强光吸收并伴随分子间能量转移,使其成为用于共形集成、基于织物的太阳能收集器的有竞争力的光敏材料。
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.
