Acylated 2-(N-arylaminomethylene)benzo [b] thiophene-3(2H)-Ones: Molecular Switches with Varying Migrants and Substituents

摘要

Synthesis and properties of photochromic acylated 2-(N-arylaminomethylene)benzo[b]thiophene-3(2H)-ones are described. Their structure largely depends on the nature of acyl migrant and in a less degree on N-aryl substituent.
