| Outline of Final Research Achievements |
Considerable increase of association degree of oligomers of the dicyano-gold (I) complex formed in the aqueous solution and the luminescence quantum yield was found by addition of coexisting salts. Particularly significant effects were observed when tetraethyl ammonium and relevant cationic polymers were added. Analysis of concentration dependence and emission wavelength revealed that associate species from pentamer to octamer were generated. In contrast, it was revealed that association was inhibited in tetracyanoplatinum complexes with coexisting species of quaternary ammonium cations.
We measured the nuclear wave packet motions of these large oligomers by time-resolved spectroscopic measurement and found that an extremely large beat signal was measured. By analysis of the oscillations, detailed assignments of the observed absorption bands for the oligomers was made.
