[Display omitted] •Recent advances in electroluminescence of oligonuclear complexes are reviewed.•The use of oligonuclear complexes as phosphorescent dopants is highlighted.•Oligonuclear metal complexes exhibit highly efficient photoluminescence.•The light-emitting devices are fabricated through solution process.•The solution-processed OLEDs exhibit high-efficiency electroluminescence. More and more oligonuclear metal complexes have been used as light-emitting materials for the fabrication of high-efficiency organic light-emitting diodes (OLEDs). This review article is focused on highlighting recent advances in the design of luminescent oligonuclear metal complexes and the use as phosphorescent dopants to achieve efficient electroluminescence. The easy accessibility at mild conditions and the strong resistance to thermal and irradiation degradation make phosphorescent metal cluster complexes have great potential to attain various colored electroluminescence for practical application in flat panel display and daily lighting.
