Photoswitchable molecules are highly requested compounds in various fields and in particular biomedicine. The urgent modern task of photopharmacology (emerging approach in medicine) is design of molecules that have both photoswitchable and bioacti...

Aggregation‐Induced Emission‐Active Donor‐substituted Aroyl‐S,N‐Ketene Acetals via Nucleophilic Amine Base Attack
Von Wiley-VCH zur Verfügung gestellt
Donor-substituted aroyl-S,N-ketene acetals can be rapidly obtained by nucleophilic attack of triethylamine at the acid chloride with concomitant decarbonylation followed by addition-elimination reaction of in situ generated enamines. These potent chromophores exhibit intensive solid-state emission and pronounced AIE (aggregation-induced emission) characteristics with high quantum yields. By changing the base to diisopropylethylamine, enlarged aroyl-S,N-ketene acetal bi- and trichromophores comprising are easily accessible.
