New Synthesis of Highly Potential Efficient Bluish‐Green Electroluminescent Materials Based on 1,3,4‐Oxadiazole‐triazolopyridinone‐carbazole Derivatives for Single‐Layer Devices.

Abstract

Devices. -The title carbazole hybrids (VI) are obtained by introducing carbazole, pyridine, and triazolopyridinone moieties into the oxadiazole building block. These chromophores play assistant roles in controlling fundamental photolytic process, due to the electron-donating nature, excellent photoconductivity, and flexible structure properties. Spectroscopic studies and the measurements of cyclic voltammogram indicate that hybrids (VI) are highly efficient bluish-green electroluminescent materials.
