Trapping intermediate MLCT states in low-symmetry {Ru(bpy)} complexes
(Royal Society of Chemistry, 2017-08)
The picosecond excited state dynamics of [Ru(tpm)(bpy)(NCS)]+ (RubNCS+) and [Ru(tpm)(bpy)(CN)]+ (RubCN+) (tpm = tris(1-pyrazolyl)methane, bpy = 2,2′-bipyridine) have been analyzed by means of transient absorption measurements ...
Structural, electronic and magnetic properties of copper(I) cubic clusters
(Elsevier Ltd, 2020-11-02)
We report the molecular and electronic structure, and the calculated electronic excitation energies, using the time dependent density functional methodologies (TD-DFT), and the induced magnetic field (Bi) of a series of ...
Qualitatively and quantitatively different solvatochromism of the MLCT and MMCT absorption bands of centrosymmetric acceptor-bridged diiron (II, II) and diiron(III, II) cyanide complexes
(Elsevier Science Sa, 2002-07)
The energies of the metal-to-ligand charge transfer (MLCT) and metal-to-metal charge transfer (MMCT) absorption bands of a number of heterocycle-bridged diiron(II, II) homovalent and diiron(III, II) mixed-valent complexes ...
Synthesis, characterization, spectroscopic and electrochemical studies of donor–acceptor ruthenium(II) polypyridine ligand derivatives with potential NLO applications
(Elsevier, 2015)
In this work we report the preparation of six new donor–metal–acceptor (D–M–A) type complexes of
ruthenium(II) with the highly absorbing ‘‘chromophoric’’ ligand 4,40-bis(2-(4-methoxyphenyl)styryl)-
2,20-bipyridine, ...
Coexistence of MLCT Excited States of Different Symmetry upon Photoexcitation of a Single Molecular Species
(American Chemical Society, 2019-02)
Photoexcitation of [Ru(tpy)(bpy)(μ-CN)Ru(py) 4 Cl] 2+ ([RuRu] 2+ ) at 387 nm results in the population of two 3 MLCT excited states of different symmetry that coexist on the nanosecond scale. Common to both states is an ...
Propriedades fotofísicas de complexos heterolépticos de Ir(III) e heterobimetálico Ir(III) – Eu(III) emissores no deep-red para aplicação em concentradores solares luminescentes
(Universidade Estadual Paulista (Unesp), 2022-04-04)
A Energia solar é uma das fontes de energia renováveis que mais se destaca devido à sua disponibilidade em função do intenso fluxo de irradiância solar sobre a Terra. Sua conversão em eletricidade é feita por dispositivos ...
Fine tuning of MLCT states in new mononuclear complexes of ruthenium(II) containing tris(1-pyrazolyl)methane, 2,2′-bipyridine and aromatic nitrogen heterocycles
(Wiley VCH Verlag, 2005-01)
The syntheses of new mononuclear ruthenium(II) complexes of the type: [Ru(bpy)(L)(tpm)](PF6)2 {tpm = tris(1-pyrazolyl)-methane; bpy = 2,2′-bipyridine; L = pz (pyrazine; 1), 4,4′-bpy (4,4′-bipyridine; 2), and bpe ...
A Hole Delocalization Strategy: Photoinduced Mixed-Valence MLCT States Featuring Extended Lifetimes
(American Chemical Society, 2019-05)
Bimetallic trans-[RuII(tpm)(bpy)(μNC)RuII(L)4(CN)]2+, where bpy is 2,2′-bipyridine, tpm is tris(1-pyrazolyl)methane and L = 4-methoxypyridine (MeOpy) or pyridine (py), was examined using ultrafast vis-NIR transient absorption ...
