Novel naphtho[2,3-c][1,2,5]thiadiazole derivative for non-doped small molecular organic red-light-emitting diodes

摘要

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 intermolecular pi-pi 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.
