d10 Among the transition metal complexes, gold (I) complexes display a luminescent transition metal complexes
stomach and applications such as chemical sensors are expected 29-35. Gold complex strength at the molecular aggregation system
from that show has emission, can be expected deployment to the solid-state light-emitting device. Such
the luminescent metal complexes, having a metal ion such as gold (I) of silver in addition to (I) or copper (I)
have also been reported. Complex containing a heavy atom ions induced magnetic moment of the molecule
for larger spin based on magnetic interaction of electrons and atomic nuclei - orbit interaction
also increases for, easily form a triplet (heavy atoms effect). Molecules emission
in the course of, excited phosphorescence there from the fluorescent and excited triplet state from the singlet state
is, each generation probability of excitons in principle in electroluminescent 1: 3 Dearuko
and is Are known. Therefore, among all excitons fluorescent light-emitting material has been produced, the emission
is 25% at maximum to participate in. Meanwhile, the triplet excitons in addition to the singlet
case of phosphorescent light-emitting material emission also occurs, the internal quantum efficiency of up to 100% in principle
since it is possible to reach, and higher than the fluorescent material It shows the luminous efficiency. Emitting
Among transition metal complexes, complexes with gold metal than the case of using silver or copper
strong interaction, stable tend to form a complex. In addition, light emission of the gold complexes
are known to be due to intermolecular interactions between the complex, acting between the gold complex
as the main interactions, Oya-kin interacts with the gold atoms and the π-conjugated molecules between gold atoms According to the
36-46 that Au-π interaction and the like.
