The ability to process conjugated polymers via aqueous solution is highly advantageous for reducing the costs and environmental hazards of large scale roll-to-roll processing of organic electronics. However, maintaining competitive electronic properties while achieving aqueous solubility is difficult for several reasons: (1) Materials with polar functional groups that provide aqueous solubility can be difficult to purify and characterize, (2) many traditional coupling and polymerization reactions cannot be performed in aqueous solution, and (3) ionic groups, though useful for obtaining aqueous solubility, can lead to a loss of solid-state order, as well as a screening of any applied bias. As an alternative, we report a multistage cleavable side chain method that combines desirable aqueous processing attributes without sacrificing semiconducting capabilities. Through the attachment of cleavable side chains, conjugated polymers have for the first time been synthesized, characterized, and purified in organic solvents, converted to a water-soluble form for aqueous processing, and brought through a final treatment to cleave the polymer side chains and leave behind the desired electronic material as a solvent-resistant film. Specifically, we demonstrate an organic soluble polythiophene that is converted to an aqueous soluble polyelectrolyte via hydrolysis. After blade coating from an aqueous solution, UV irradiation is used to cleave the polymer’s side chains, resulting in a solvent-resistant, electroactive polymer thin film. In application, this process results in aqueous printed materials with utility for solid-state charge transport in organic field effect transistors (OFETs), along with red to colorless electrochromism in ionic media for color changing displays, demonstrating its potential as a universal method for aqueous printing in organic electronics.

印刷有机电子产品的水性加工：具有多级可裂解侧链的共轭聚合物
经由水溶液处理共轭聚合物的能力对于降低有机电子的大规模卷对卷处理的成本和环境危害是非常有利的。然而，由于以下几个原因，很难在保持水溶性的同时保持竞争性电子性能：（1）具有极性官能团且具有水溶性的材料难以纯化和表征；（2）许多传统的偶联和聚合反应无法在水性溶液中进行溶液；和（3）离子基团，尽管可用于获得水溶性，但会导致固态有序损失，以及任何施加的偏倚的筛选。作为备选，我们报告了一种多级可裂解侧链方法，该方法结合了所需的水处理特性而又不牺牲半导体性能。通过连接可裂解的侧链，共轭聚合物首次在有机溶剂中合成，表征和纯化，转化为水溶性形式以进行水处理，并进行最终处理以裂解聚合物侧链并留下所需的电子材料作为耐溶剂膜。具体而言，我们证明了有机可溶的聚噻吩通过水解转化为水可溶的聚电解质。从水溶液中刮涂后，使用紫外线照射裂解聚合物的侧链，从而形成耐溶剂的电活性聚合物薄膜。在申请中，
