摘要：
Four extensively fluorinated tetraphenylethylenes (TPE) and one extensively fluorinated triphenylethylene have been synthesized using combinations of copper-catalyzed C-H functionalization reactions and Stille coupling reactions. Surprisingly, in contrast to the parent TPE, these compounds show little to no aggregation-induced emission (AIE). Instead, photocyclization into fluorinated phenanthrene products occurs. Effects of solvent and oxygen on the yield and selectivity of this photo-cyclization have been examined.
