quaterthiophene amphiphiles containing one 3,4-ethylenedioxythiophene (EDOT) and a single strong twist in the scaffold. Planarizable push–pull oligothiophene amphiphiles have been introduced recently as conceptually innovative fluorescent probes that sense the fluidity and the potential of lipid bilayer membranes. The “hyper-twisted” EDOT probes respond to planarization and restricted rotational freedom with
我们报告推挽的设计,综合和评估 四噻吩 包含一个的两亲 3,4-乙撑二氧噻吩(EDOT)和脚手架上的单个强烈扭曲。可平面推挽寡聚噻吩两亲物最近作为一种概念上新颖的荧光探针被引入,可检测脂质双层膜的流动性和潜力。“超扭曲” EDOT探头分别响应平面化和受限的旋转自由度,并出现红移和激发光谱中振动精细结构的变化。在溶液中,发现相当弱的溶剂致变色和显着的热致变色。平面化和有限的旋转自由度提供了对脂质双层膜性质和流动性的精妙灵敏度,包括相变的比率检测。这些独特的特性会削弱对膜电位的感测,但仍然是可能的。
