Excited-state distortions determined from structured luminescence of nitridorhenium(V) complexes.

Ultrafast Luminescence Decay in Rhenium(I) Complexes with Imidazo[4,5-f]-1,10-Phenanthroline Ligands: TDDFT Method

The interpretation of the ultrafast luminescence decay in [Re(Br(CO)3(N^N)] complexes as a new group of chromophoric imidazo[4,5-f]-1,10-phenanthroline ligands, including 1,2-dimethoxy benzene, tert-butyl benzene (L4) and 1,2,3-trimethoxy benzene, tert-butyl benzene (L6), was studied. Fac-[Re(Br(CO)3L4 and L6] with different aryl groups were calculated in singlet and triplet excited states. The...

Excited-state distortions of cyclometalated Ir(III) complexes determined from the vibronic structure in luminescence spectra.

The luminescence spectra of [(tpy)(2)Ir(CN-t-Bu)2](CF(3)SO(3)) in methylcyclohexane glass and frozen n-nonane at 15 K reveal well-resolved vibronic fine structure. The vibronic peaks are assigned by comparison with the vibrational frequencies obtained from Raman and IR spectra and those obtained using DFT electronic structure calculations. The magnitudes of the distortions along the normal coor...

Synthesis and Luminescence of RhIII ( phpy ) 2 ( S ∪ E ) Complexes

Complexes of the general composition Rh(phpy)2(S∪E) with phpy− = 2-(2-pyridyl)phenyl and S∪E− = diethyldithiocarbamate, 2-pyridinethiolate and 2-quinolinethiolate were prepared and characterized. The complexes with S∪E− = diethyldithiocarbamate and 2-pyridinethiolate show a low-temperature luminescence which originates from a phpy ππ∗ intraligand triplet. For the complex with S∪E− = 2-quinoline...

Luminescence of Dimerie Tl(I)-Complexes: Metal-Metal Interaction in the Electronically Excited State

Study of Luminescence Quenching of Tri's(4, 4'. di-ohenyl-2, 2'- bi-pyridine Ruthenium (II) Chloride & Tris(4, 7-Diphenyl-1, 10- Phe.nanthroline)

Luminescence quenching of [Ru(diphenyl-bpr)3]Cl2 and of [Ru(diphenyl-phen)3]Cl2 by 19 transition metal complexes is reported. These complexes have properties which permit them to supplement the widely used [Ru9bpy)3] 2+ and [Ru(phen)3] 2+ sensitizers. The excited state of these complexes can also be tuned significantly by solvent variation. Quenching is predominantly by diffusion. Decay times, ...
