The invention relates to the technical field of organic luminescent materials, in particular to a spirofluorene compound and a luminescent device for the spirofluorene compound. The spirofluorene-xanthene compound disclosed by the invention is selected from the compound as shown in the general formula I, wherein Y1 and Y2 independently represent hydrogen, electron withdrawing groups or electron donating groups; and at least one substituent in X1 and X2 is the substituent as shown in the general formula II. A spirofluorene structure and a xanthene structure in the compound disclosed by the invention form a dihedral angle which is about 90 degrees, the M group has the effect of further dispersing LUMO orbits, thereby separating HOMO-LUMO orbits to obtain ideal Delta EST. Furthermore, the spirofluorene-xanthene compound disclosed by the invention has a stable rigid structure, and endows the materials with relatively high molecular stability.
