单壁碳纳米管中的有机色心在量子技术、生物化学传感、生物成像等方面得到了广泛的研究。可扩展的OCCS的精确国产化将给下一代光电子学带来一场革命，但到目前为止，这仍然是一个巨大的挑战。在这里，开发了一种可扩展的、低成本和通用的光图案化策略，通过结合光学活性重氮化学和微接触印刷方法在(6，5)手性SWCNT薄膜上的所需位置植入OCCS。值得注意的是，可以通过改变用于构图化学的溶剂来调节图案，从而控制不同区域的重氮盐的重量。系统的研究表明，溶剂的性质(极性和蒸汽压)、墨水的体积和浓度、图案化方法和MeODz的浓度都对可调图案化有贡献。这种空间精确和溶剂可调的光图案化技术简单、可扩展，并且可以集成其他色心化学和2D过渡金属二卤化物，以实现具有高器件一致性和分子水平可操纵性的下一代芯片集成纳米电子学和光电子学。
Organic color-centers (OCCs) in single-walled carbon nanotubes (SWCNTs) have been intensively investigated for quantum technologies, bio- and chemical sensing, bioimaging. The precise localization of OCCs at a scalable manner will bring about a revolution into next generation optoelectronics, which, however, remains a great challenge till now. Here, a scalable, low cost and universal photo-patterning strategy is developed to implant OCCs at desired locations on (6,5)-chirality SWCNT films by combining optically active diazonium chemistry and micro-contact printing methods. Notably, the patterns can be tunable by changing the solvents used for the patterning chemistry, affording control over the weight of diazonium salts at different regions. A systematic investigation reveals that the solvent properties (polarity and vapor pressure), the volume and concentration of ink used, the patterning methods, and the concentration of MeODz all contribute to the tunable patterning. This spatial accurate and solvent tunable photo-patterning technique is simple, scalable, and amenable to the integration of other color center chemistries and 2D transition metal dichalcogenides for the next-generation chip-integrated nanoelectronics and optoelectronics with high device uniformity and manipulability at molecular level.
