Abstract
The results of simulation indicate that biphenyl (BIP) is one of the original materials of dibenzothiophene (SF) and dibenzofuron (OF). It has the fundamental structure of SF and OF. As the radicals that attract electron, its two aromatic nucleuses influence each other, which make the α-H active. The strong electronegative sulphur or oxygen atoms attack the two places of the two aromatic nucleuses, seize the hydrogens and form H2S or H2O, the other sulphur or oxygen atoms attacking the two places which have lost hydrogens can put up a bridge and make the BIP molecule which can freely turn become a stable SF or OF molecule. So SF and OF have no definite relation with fluorene (F).
