organocatalysts and redox active polymers. However, the self‐assembly of amphiphilic aminocyclopropenium ions remains challenging. The first deltic ionic liquid crystals based on aminocyclopropenium ions have been developed. Differential scanning calorimetry, polarizing optical microscopy and X‐ray diffraction provided insight into the unique self‐assembly and nanosegregation of these liquid crystals. While
氨基环丙烯离子作为有机催化剂和氧化还原活性聚合物引起了广泛关注。然而,两亲性氨基环丙烯离子的自组装仍然具有挑战性。第一个基于氨基环丙烯离子的三角离子液晶已经开发出来。差示扫描量热法、偏光光学显微镜和 X 射线衍射提供了对这些液晶独特的自组装和纳米偏析的深入了解。虽然小头基与线性对烷氧基苯基单元的组合导致双层型近晶中间相,但楔形单元导致柱状中间相。当氨基环丙烯头部基团的尺寸和多亲性增加时,形成层状相。
