We design a novel class of excited-state locked GFP chromophores by introducing an amine group at the double -bond and a difluoroboryl bridge. We show that these chromophores intrinsically exhibit a very large Stokes shift of 1 eV. Further tuning through chemical modifications of their aryl substituents makes them environmentally sensitive.
我们通过在双键处引入胺基和二氟硼桥,设计了一类新型的激发态锁定绿色荧光蛋白发色团。我们发现这些发色团本质上表现出高达1电子伏特的非常大的斯托克斯位移。通过对其芳基取代基进行化学修饰进一步调节,使它们对环境敏感。
