The spiro aromatic organic compounds are configured to have at least three planar and substantially linear moieties and generally have high vitrifiable temperature and high melting point (above 300 ℃), which provide thermal stability to organic electroluminescence (EL) devices. They are favorable in making the organic EL devices and do not need complicated equipments. So they may help to reduce the cost and are better in the preparation of larger size devices. The recent progress in electroluminescence device including spiro compounds of fluorene and anthracene is discussed in this paper. The synthetic methods of double-spiro and single-spiro organic compounds together with EL devices are described in detail. A brief introduction about spiro compounds including Si elements is also reviewed.

Key words: single-spiro compound, double-spiro compound, electroluminescence, fluorene
