The synthesis, characterization, photophysical and redox properties of a dinuclear complex Zn 2 (AMOX) 4 (AMOX = 4‐bromo‐ N , N′ ‐diphenylbenzamidinate N ‐oxide) are highlighted. This compound is a first example of a novel class of aggregation‐induced emission (AIE) materials. Noticeably, solution‐processed white‐green organic light‐emitting diodes were fabricated using this complex as dopant in a co‐host matrix in the emissive layer. A luminance efficiency and power efficiency as high as 1.12 cd/A and 0.30 lm/W were obtained, respectively. The characteristics of this complex: high solubility, thermal stability, AIE behaviour, ease of synthesis, tunability options, and low‐cost, reveal altogether great potential for the development of this new family of compounds as materials for applications in optoelectronic devices.
