有机半导体是一族π共轭化合物，用于许多应用，例如显示器、生物电子学和热电学。然而，它们对加工引起的污染的敏感性尚不清楚。研究表明，迄今为止报道的许多有机电子器件可能被无意污染，从而影响其性能、吸水性和薄膜特性。核磁共振波谱用于检测和量化源自手套箱气氛和设备制造过程中使用的常见实验室消耗品的污染物。重要的是，对污染源的深入了解可以建立清洁制造协议，并制造具有改进性能和稳定性的有机场效应晶体管（OFET）。这项研究强调了无意污染物在有机电子器件中的作用，并证明需要满足某些严格的加工条件，以避免科学误解、确保器件的可重复性并促进性能稳定性。本文使用的实验程序和条件是溶液加工有机半导体领域许多团体所使用的典型实验程序和条件。因此，对污染影响的深入了解可能广泛适用于 OFET 的研究，也适用于基于这些材料的其他器件的研究。
Organic semiconductors are a family of pi‐conjugated compounds used in many applications, such as displays, bioelectronics, and thermoelectrics. However, their susceptibility to processing‐induced contamination is not well understood. Here, it is shown that many organic electronic devices reported so far may have been unintentionally contaminated, thus affecting their performance, water uptake, and thin film properties. Nuclear magnetic resonance spectroscopy is used to detect and quantify contaminants originating from the glovebox atmosphere and common laboratory consumables used during device fabrication. Importantly, this in‐depth understanding of the sources of contamination allows the establishment of clean fabrication protocols, and the fabrication of organic field effect transistors (OFETs) with improved performance and stability. This study highlights the role of unintentional contaminants in organic electronic devices, and demonstrates that certain stringent processing conditions need to be met to avoid scientific misinterpretation, ensure device reproducibility, and facilitate performance stability. The experimental procedures and conditions used herein are typical of those used by many groups in the field of solution‐processed organic semiconductors. Therefore, the insights gained into the effects of contamination are likely to be broadly applicable to studies, not just of OFETs, but also of other devices based on these materials.
