First synthesis of N-arylated oxoindirubin derivatives and evaluation of their optical and photochemical properties

The development of synthetic approaches towards N -functionalization of indigoid dyes attracts growing interest because of their significant application potential in material science and biology. In this work, we present the first synthesis and characterization of N -arylated oxoindirubin derivatives. Furthermore, we provide the study of their optical and photochemical properties under various conditions.
