设计并合成了一种由π共轭和离子部分组成的新型电致变色分子。它形成纳米偏析的近晶相，其中咪唑鎓盐的离子传导层位于苯基三噻吩部分的空穴传输层之间。在没有电解质溶液的情况下，在该化合物的本体液晶态中观察到电致变色。在这种纳米偏析的近晶相中，电极上快速形成双电层。因此，空穴从电极注入，导致π共轭部分氧化。
A new electrochromic molecule comprised of pi-conjugated and ionic moieties has been designed and synthesized. It forms a nanosegregated smectic phase in which ion-conductive layers of imidazolium salts are located between hole transport layers of phenylterthiophene moieties. Electrochromism is observed in the bulk liquid crystal state of this compound without an electrolyte solution. In this nanosegregated smectic phase, an electrical double layer is formed rapidly at the electrode. Consequently holes are injected from the electrode, resulting in oxidation of the pi-conjugated moieties.
