The invention discloses a hexa-heterocycle derivative and an organic electroluminescent device thereof, and relates to the technical field of organic photoelectric materials. Compared with the prior art, the hexa-heterocycle derivative has the advantages that the hexa-heterocycle derivative shown in the structural formula I has the good electron acceptor feature, the hexa-heterocycle derivative serves as a dopant to be mixed with a substrate material having the electron donor feature, and has the relative high specific conductance at the relatively low doping concentration, holes are generatedin the electron transferring process, the hole migration rate is effectively improved, and the hexa-heterocycle derivative has the relatively high hole injection efficiency. The hexa-heterocycle derivative serves as the organic electroluminescent device of an organic matter layer, has the relatively low driving voltage and the high luminescent efficiency, and has long service life.
