1. Ultrafast colorimetric humidity-sensitive polyelectrolyte coating for touchless control
Mater. Horiz., 2017, Advance Article
DOI: 10.1039/C6MH00317F
Researchers in Australia, China and Canada have shown a simple and cheap touchless control system that is sensitive to humidity change. The system uses a polyelectrolyte multilayer coating that can rapidly change colour depending on changes in the local humidity. This modulation of outputted light can be converted to an input electrical signal of a touchless system. The approach offers straightforward device control using, for example, human breath or the close proximity of a fingertip, and it opens a new potential route to convenient, user-friendly and hygienic touchless systems, with applications in a wide variety of areas, from the automotive industry to smart buildings.
澳大利亚、中国和加拿大的研究人员展示了一种感应湿度变化的非接触控制系统,此方法既简单又经济有效。该系统采用聚电解质的多层涂层,能根据本地湿度的变化而迅速改变颜色。调制输出的光又被转换为电信号输入到非接触式系统中。该系统可应用于直接控制设备中,比如利用人的呼吸或是指尖靠近来进行控制。这为生产方便、卫生、用户友好的非接触系统提供了一个新的潜在途径,并拥有从自动化生产到智能建筑在内的广阔应用空间。

2. Embedding electron-deficient nitrogen atoms in polymer backbone towards high performance n-type polymer field-effect transistors
Chem. Sci., 2016, 7, 5753-5757
DOI: 10.1039/C6SC01380E
Scientists from Peking University have developed a donor–acceptor (D–A) conjugated polymer AzaBDOPV-2T with a low LUMO level, with sp2-nitrogen atoms embedded in an isatin unit, providing high electron mobilities tested under ambient conditions. These results demonstrate that embedding electron-deficient sp2-nitrogen in conjugated backbones is an effective approach to develop n-type polymer semiconductors with high performance.
北京大学裴坚教授课题组开发了一种低LUMO能级的供体-受体(D-A)型共轭聚合物AzaBDOPV-2T,其中sp2杂化氮原子嵌入靛红,使其在室温测试条件下具有高的电子迁移率。研究结果表明,在共轭骨架上引入缺电子sp2氮原子是获得高性能n型半导体聚合物的有效方法。
