Complexation of iminocoumarin derivatives with BF3·OEt2 provides novel N⁁N boron(III) dyes exhibiting high absorption coefficients and quantum yields as great as 81%. The excellent chemical stability of these dyes enables the grafting of Boranil or Bodipy units to give derivatives in which the Borico subunit can act either as an energy acceptor or as an antenna for a red emitting fluorophore.
亚氨基香豆素衍生物与 BF3-OEt2 的络合提供了新型 N⁁N硼(III)染料,具有很高的吸收系数和高达 81% 的量子产率。由于这些染料具有出色的化学稳定性,因此可以接枝 Boranil 或 Bodipy 单元,从而得到 Borico 亚单元可以作为能量接受体或红色发射荧光团天线的衍生物。
