Abstract:
Biphenylene bridged bisaroyl-S,N-ketene acetals can be readily synthesized by a one-pot Masuda borylation-Suzuki arylation (MBSA) sequence, thus, yielding a library of 20 bisaroyl-S,N-ketene acetals with tunable solid-state emission and aggregation-induced enhanced emission characteristics depending on the para substituents in the starting material. Potential applications as fluorometric probe of alcoholic beverages are outlined.
