Efficient red‐light emission is obtained with a novel, non‐doped, naphtho[2,3‐ c ][1,2,5]thiadiazole (NTD) derivative (see figure). This material does not contain strong donor groups so dipole–dipole interactions and inter‐molecular π–π stacking can be substantially suppressed. Non‐doped pure‐red OLEDs with high efficiency have been prepared indicating that this material has great potential in the fabrication of high‐performance red OLEDs.
