Abstract: The present invention discloses lanthanide series bisphthalocyanine complex compounds, wherein chemically and thermally stable side chains effective for the development of a functional film due to generation of solubility and liquid crystallization in a solvent.The compounds according to the present invention having no reacting positions at side chains thereof possess electrochromic properties and further possess excellent electrochemical characteristics. Moreover, these compounds are soluble in a solvent and show discotic liquid crystal phase. Therefore, these compounds are very effective for the development of a functional film.

Abstract: Octasubstituted tetraphyrazinotetraazaporphrazine and compositions forming an electron acceptable discotic liquid crystal phase are disclosed. Said compounds and the metal complexes are easily soluble in an organic solvent such as chloroform or dichloromethane etc and are insoluble in acetone and alcohols; and therefore a columnar phase by silica gel/dichloromethane, recrystallization from tetra-hydrofuran or refining through solid liquid extraction by acetone is possible. Furthermore, stability in a giant molecular can be expected and a functional membrane can be formed by a solution cast method etc., thereby employing as an electon or photoelectron material or an indication element.
