The structure of the electron shells and atomic nuclei of the rare earths are determinative to their own properties and compounds, and many unique properties of them determine their applications in turn. So it is worthwhile to study the properties and structures of rare earth compounds and to explore their new applications as new materials. In this article, the structures and semiconducting properties of diiodofluorescein (diIFluo), tetraiodofluorescein (tetraIFluo) and their rare earth complexes are described for the first time.展开更多
