Palladium catalysed coupling of the 2-iodoBODIPY 3 with a range of anilines and a primary alkylamine succeeds in generating the corresponding 2-aminoBODIPYs. These 2-aminoBODIPY derivatives are non-emissive and quantum chemical calculations and electrochemistry are consistent with charge transfer from the amine substituent. Attenuation of this charge transfer pathway by conversion of the 1,2-phenylenediamine derivative 9 into the corresponding benzimidazolone 10 restores the fluorescence and has been used as the basis for a fluorescence sensor for phosgene.

钯催化胺化合成2-aminoBODIPYs

钯催化的2-ioBODIPY 3与一系列苯胺和伯烷基胺的偶联成功地产生了相应的2-aminoBODIPY。这些2-aminoBODIPY衍生物是非发射性的，并且量子化学计算和电化学与胺取代基的电荷转移是一致的。通过将1，2-苯二胺衍生物9转化为相应的苯并咪唑酮10来减弱该电荷转移途径，从而恢复了荧光，并已被用作光气荧光传感器的基础。
