Abstract
A series of new cationic ortho-metalated Pd(II) complexes of general formula [(C<^>N)Pd(N<^>N)X (H(boolean AND)N = 2-phenylpyriditie, H(PhPy) or benzo[h]quinoline, H(BhQ); N boolean AND N = ethylenediamine, 2,2'-bipyridiiie, 1, 10-phenanthroline. N, N,N,N'-tetramethylethyleiiediamine, 4,4'-dimethyl-2,2'-bipyridine, 4,7-dimethyl-1,10-pheiiaiithrolitie,. or 4,4'-dinonyl-2,.2'-bipyridine-. X = CF(3)SO(3)) are reported. Photophysical characterization of these species indicates that electronic transitions are prominently cyclometalating ligand-localized in character and nearly unaffected by the polarity of solvent in which the spectra are recorded.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
