Green, solvent-free synthesis of divinylbenzo[ c ][1,2,5]thiadiazole emitters via the hand-grinding Horner–Wadsworth–Emmons reaction for high-performance OLEDs

Divinylbenzo[ c ][1,2,5]thiadiazole (DBTDz)-based compounds were investigated as electroluminescent emitters for organic light-emitting diodes (OLEDs), covering emission wavelengths from yellow to near-infrared (NIR).
