We present a series of visible-light-absorbing azobenzene photoswitches with cis-lifetimes ranging from one second to three days. We combine ortho-fluorination to control the cis-lifetimes, and ortho-amination to boost the visible-light absorption. The synthesis is accomplished by selectively replacing one or more ortho-fluorines with amines in the ortho-fluoroazobenzene precursors.

通过邻位氟化和氨基化结合控制偶氮苯的光开关

我们提出了一系列可见光吸收的偶氮苯光电开关，其顺式寿命从一秒到三天不等。我们结合使用邻氟化来控制顺式寿命，并结合邻氨基化来提高可见光吸收率。合成通过选择性地替换一个或多个实现的邻位与胺-fluorines邻-fluoroazobenzene前体。
