A styryl Seoul-Fluor (SF) skeleton was rationally designed by introducing an olefin unit at the C-9 of 1,2-dihydropyrrolo[3,4-β]indolizin-3-one via regioselective direct C–H activation, affording average 39 nm of bathochromic shift.
通过在1,2-二氢吡咯并[3,4-β]吲哚啉-3-酮的C-9位置引入烯烃单元,通过区域选择性直接C-H活化,合理设计了一种苯基首尔荧光(SF)骨架,产生平均39纳米的红移。
