A family of easily accessible light-activated hydrazone switches has been developed having thermal half-lives of up to 2700 years! Structure-property analysis shows that replacing the rotor pyridyl group of our typical hydrazone switch with a phenyl one leads to the long-lived negative photochromic compounds. The switching properties of the hydrazones in both toluene and DMSO were assessed offering insights into the kinetics and thermodynamics of the switching process.
已经开发出了一系列易于获得的光激活腙开关,其热半衰期长达 2700 年!结构-性能分析表明,用苯基取代我们典型的腙开关的转子吡啶基会导致长寿命的负光致变色化合物。评估了腙在甲苯和 DMSO 中的开关性能,为开关过程的动力学和热力学提供了深入了解。
