Etherified aroyl-S,N-ketene acetals can be easily synthesized via a unique one-pot addition-elimination-Williamson etherification sequence. While the chromophore remains the same, derivatives exhibit significant color tuning in solid-state emission and AIE characteristics, with a hydroxy-methyl derivative serving as an easily accessible mono-molecular aggregation-induced white-light emitter.
Etherified aroyl-S,N-ketene acetals are readily synthesized by a novel one-pot addition-elimination-Williamson-etherification sequence. Although the underlying chromophore remains constant, derivatives show pronounced color-tuning of solid-state emission and AIE characteristics, whereas a hydroxy-methyl derivative represents an easily accessible mono molecular aggregation-induced white-light emitter.
