Radical-Containing Block Copolymers: Microphase Separation and Charge Storage/Transport Modulation in the Organic Thin Film Devices

将氧化还原活性自由基和离子对用于电荷补偿引入微相分离区域，以调节电荷注入/输运特性，特别是对于一种新的有机非挥发性存储器设计。通过逐步控制自由基聚合或在嵌段共聚物中选择性地掺入Tempo-离子液体来制备自由基/离子嵌段共聚物，构建了明确的自由基结构域和离子结构域及其界面。研究了其形态与记忆特性之间的关系。

Redox-active radicals and ion pairs for charge compensation were incorporated into the microphase-separated domains, to modulate charge-injection/-transport properties, especially for a new design of organic nonvolatile memory. Radical/ion-containing block copolymers were prepared via stepwise controlled radical polymerization, or selective incorporation of TEMPO-ionic liquids into block copolymers, which construct the well-defined radical- and ionic-domains, and their interface. The correlation between the morphology and memory characteristics was investigated.
