DESIGN, SYNTHESIS, AND EVALUATION OF A DYE LIBRARY : GLASS-FORMING AND SOLID-STATE LUMINESCENT MEROCYANINES FOR FUNCTIONAL MATERIALS

A highly efficient multicomponent reaction based on the little-known formylating agent dimethylformamide in acetic anhydride led to a multitude of dyes of the indoline (1) and of the thiazole type (2), whose systematic evaluation revealed desired and surprising solid-state properties.
