Modular three-component synthesis, photophysics, and electronic structure of solid-state and aggregate luminescent α-sulfenylated aroyl-S,N-ketene acetals

α-Sulfenylated aroyl-S,N-ketene acetals are accessible from acyl chlorides, benzothiazolium salts, and N-thiosuccinimides via consecutive one-pot three-component synthesis in a modular fashion. The resulting merocyanines are prone to equilibrating E–Z-isomerization in solution, whereas preferred configurations can be f...
