论文摘要
同时优化有机电子材料的性能,加工性和制造成本是阻碍破坏性应用的发展的持续折衷来源。在这项工作中,我们确定了一种策略,即通过掺入完全解决,无水和成本效益的技术来实现最基准的半导体聚合物之一的记录电导率值。使用市售的电子受体作为刘易斯酸和氧化剂,已经实现了高达21 s/cm的聚(3-己基噻吩)的高电导率。虽然我们管理了无水溶液处理的P3HT的三次较高的电导率,但具有非常负担得起的化学物质,近场显微镜揭示了浓度依赖性的高电导率微型域的存在,从而进一步的过程优化可能会获得更高的性能。为了永久寻求有机电子产品的较高性能,这项工作应极大地解锁应用程序的成熟,需要更高规模的加工能力,并且在当前的情况下,在理解此类材料类别的兴奋剂机制的情况下,较高的性能和新功能伴随着更高的性能和新功能。
Simultaneously optimizing performances, processability and fabrication cost of organic electronic materials is the continual source of compromise hindering the development of disruptive applications. In this work, we identified a strategy to achieve record conductivity values of one of the most benchmarked semiconducting polymers by doping with an entirely solution-processed, water-free and cost-effective technique. High electrical conductivity for poly(3-hexylthiophene) up to 21 S/cm has been achieved, using a commercially available electron acceptor as both a Lewis acid and an oxidizing agent. While we managed water-free solution-processing a three-time higher conductivity for P3HT with a very affordable/available chemical, near-field microscopy reveals the existence of concentration-dependent higher-conductivity micro-domains for which furthermore process optimization might access to even higher performances. In the perpetual quest of reaching higher performances for organic electronics, this work shall greatly unlock applications maturation requiring higher-scale processability and lower fabrication costs concomitant of higher performances and new functionalities, in the current context where understanding the doping mechanism of such class of materials remains of the greatest interest.
