The invention discloses bisphosphonic heterocyclic organic electroluminescent compounds comprising spirofluorene structures, and a synthetic method and application thereof, and belongs to the field of organic electroluminescent materials. A general structural formula of the bisphosphonic heterocyclic organic electroluminescent compounds is as shown in the description, wherein X represents O, S or Se, and R is shown in the description. The organic electroluminescent compounds provided by the invention can be applied to luminescent layers of organic electroluminescent devices; luminescent properties of corresponding devices can be regulated by simple chemical modification of phosphine atoms; the organic electroluminescent compounds are excellent in thermal stability; through the spirofluorene structures, the packing effect among molecules can be effectively reduced, so that the efficiency of the corresponding organic electroluminescent devices can be significantly improved, and the service lives of the corresponding organic electroluminescent devices can be significantly prolonged.
