Metal complexes of organic ligands with the nature of the metal ions and organic matter having a property of inorganic
are compounds combining. Such metal complexes, both organic and inorganic materials
as a material having both properties, optical functions such as light emission, electronic features such as photoelectric conversion,
since the catalytic function, the expression of functions A wide variety such as a magnetic feature can be expected, Sama-za
1-20 has been applied in the Mana field. Among these functions, in the present study of the metal complex
is focused on light emitting property, by the controlling the electronic environment and molecular aggregation structure of the metal centers
I are possible creation of materials with diverse emission characteristics It was considered.
Colorful nature of the transition metal complex is filled to the d-orbit of the outermost shell of the transition metal ion
is derived from the electronic transition it was. Metal centers of transition metal complexes having an absorption in the visible light region
because it has an empty d-orbital, electrons between when irradiated d orbitals excitation light transition (dd Qian
to move), reaching into the excited state. Then, for example, as the red and green organic EL elements
iridium complex has been developed, intake when the place is relaxed from an excited state to a ground state
to emit energy to yield a light emission. Such transition metal complexes are conventional
to exhibit a very high emission quantum yield compared to the organic fluorescent materials are known 21, 22.
Thus, in recent years, the transition metal complexes show peculiar photochemical behavior as luminescent complexes
have been shown to be. Recently, in particular, copper, silver, platinum, has a gold ion
is a transition metal complex, has attracted much attention as organometallic complexes which exhibit phosphorescence
that.
