The small and synthetically easily accessible coumarinylmethyl backbone has been modified to generate a family of photolabile protecting groups with redshifted absorption. We relied on introducing electron‐donating groups in the 7 position and electron‐withdrawing groups in the 2‐, and 2‐ and 3 positions. In particular, we showed that the diethylamino‐thiocoumarylmethyl and the diethylamino‐coumar
小型且易于合成的香豆素甲基主链已经过修饰,可产生具有红移吸收的光不稳定保护基团。我们依靠在7位引入供电子基团,在2位,2位和3位引入吸电子基团。特别是,我们表明二乙基氨基-硫代香豆基甲基和二乙基氨基香豆基亚甲基丙二腈与青色光解开有关。它们在470–500 nm波长范围内均具有显着的解开作用截面,并且在350至400 nm之间具有较低的光吸收率。这些引人入胜的功能有利于分别使用UV和蓝青色光源执行彩色正交光激活。
