The chiroptical switching properties of a readily accessible and water-soluble diaza [4]helicene are disclosed. This zwitterionic dye displays pH-dependent absorption and emission properties and this enables a reversible turn on/off of electronic circular dichroism at 300 nm and of circularly polarized luminescence in the red region upon protonation/deprotonation.
本文报道了一种易于获得的水溶性二氮杂[4]螺旋烯的手性光开关性质。这种两性离子染料表现出pH依赖的吸收和发射性质，这使得在质子化/去质子化时，300 nm处的电子圆二色性和红色区域的圆偏振发光能够可逆地开启/关闭。
