We introduce a visible light-induced Staudinger-Bertozzi ligation photo-uncaging of a triphenylphosphine moiety with a photolabile coumarin derivative. Our action plot study examines the conversion as the function of wavelength, revealing that the uncaging process and Staudinger reaction can be triggered by green light ( < 550 nm). We further demonstrate the applicability of our approach in materials science endgroup modification of water soluble poly(ethylene glycol) and green light-induced patterning of a solid substrate.
我们介绍了一种可见光诱导的施陶丁格-贝托齐连接，用光不稳定香豆素衍生物对三苯基膦部分进行光解笼。我们的动力学研究考察了波长对转化率的影响，结果表明解笼过程和施陶丁格反应可以被绿光（ < 550nm）触发。我们进一步证明了我们的方法在材料科学中水溶性聚乙二醇的端基修饰和固体基底的绿光诱导图案化方面的适用性。
