管理和分析集中的数据存储库是解决可重复性问题、获得新见解和指导未来实验的有价值的方法，特别是在纳米材料研究领域。在这项工作中，从15篇出版物中构建了包含115个基于dpp - dt的有机场效应晶体管（OFET）的处理信息和迁移率值的数据集。定制的分类算法应用于数据集，以帮助确定降低聚合物溶液浓度的设计区域，从而更有可能提高井眼迁移率。为了证实从数据管理中获得的见解，进行的实验表明，溶液浓度对聚合物链激子相互作用和电子性能有很强的影响。在氯苯中，在临界链重叠浓度为5 g/L时制造的器件提高了空穴迁移率，并且与分类算法提供的见解很好地一致。
Curating and analyzing centralized data repositories is a valuable approach in resolving the issue of reproducibility, gaining new insights and guiding future experiments, especially in the field of nanomaterials research. In this work, a data set containing processing information and mobility values of 115 DPP-DTT-based organic field effect transistors (OFET) was constructed from 15 publications. A customized classification algorithm was applied to the data set to help identify a reduced design region for polymer solution concentration that would be more likely to result in improved hole mobility. Experiments performed to confirm the insights from the data curation exercise revealed a strong influence of solution concentration on the polymer chain excitonic interactions and electronic performance. Devices fabricated at the critical chain overlap concentration of 5 g/L in chlorobenzene resulted in improved hole mobility, and were in good agreement with the insights provided by the classification algorithm.
