Abstract

Improved performance of light-emitting devices is reported for devices containing the newly synthesized, triazole-containing polymer TRIDSB (see Figure). This fully conjugated material has a high solid-state photoluminescence quantum efficiency, unlike other triazole polymers investigated previously, and emits blue light. TRIDSB holds promise as an electron-transporting material.
