We report the design, synthesis, photoswitching and computational studies of -methyl arylazo-3,5-(di-2-pyridyl)pyrazole and its -alkyl pyridinium derivatives with an ionic center proximally located to the azo group. Besides achieving excellent photoswitching characteristics, particularly at longer wavelengths, and tuning isomer stability due to the effects of counter ions and pH, the utility of neutral and ionic photoswitches for pH modulation by light was achieved.
我们报告了对甲基芳基偶氮-3,5-(二-2-吡啶基)吡唑及其偶氮基团附近带有离子中心的烷基吡啶鎓衍生物的设计、合成、光开关特性及计算研究。除了实现优异的光开关特性,尤其是在较长波长下,并由于抗衡离子和pH值的影响调节异构体稳定性外,还实现了中性和离子型光开关用于光控pH调节的效用。
