Abstract
A series of six new rhenium(I) tricarbonyl complexes [Re(CO)3(N-N)Br] bearing sulfur-bridged dipyridyl (N-N) ligands with three different oxidation states (sulfide (S), sulfoxide (SO), and sulfone (SO2)) are described. Spectroscopic studies show that changing the oxidation state of the ligands influences the photophysical properties of the complexes, with complexes 3 and 6 containing the sulfone ligand exhibiting a lower energy MLCT absorption band tailing into the visible region. Solution-state emission measurements show that these complexes exhibit readily tunable emission energies from 480 to 610 nm, depending on the oxidation state of the sulfur bridge and the presence of substituents on the pyridyl rings. Solid-state emission measurements show that the emission is significantly red-shifted upon oxidation of the sulfur bridge to sulfone with enhanced photoluminescence quantum yield.

Abstract
Series of Re(I) carbonyls complexes were designed and synthesized to explore the impact of the triimine skeleton and number of methoxy groups attached to aryl substituents on their optoelectronic and thermal properties. The chemical structures of the prepared complexes were confirmed by 1H and 13C NMR spectroscopy, HR-MS, elemental anlsysis, and X-ray measurements. DSC measuremtns showed that they melted in the range of 198-325 °C. Some of them form stable molecular glasses with high glass transition temperatures (158-173 °C). Experimentally obtained optical properties were supported by DFT calculations. The UV-Vis spectra display a series of overlapping absorption bands in the range 200-350 nm, and much weaker broad band in the visible spectral region, due to intraligand and charge transfer transitions, respectively. All synthesized complexes were emissive in solution and in solid state as powder. Moreover, when applied in diodes, some of them exhibited ability for emission of light under external voltage with maximum of electroluminescence band located at 591-630 nm.

Abstract
![]()
The synthesis, photophysics, and
photochemistry of a linked dyad ([Re]-[NiFe2]) containing
an analogue ([NiFe2]) of the active site of [NiFe] hydrogenase,
covalently bound to a Re-diimine photosensitizer ([Re]), are described.
Following excitation, the mechanisms of electron transfer involving
the [Re] and [NiFe2] centers and the resulting decomposition
were investigated. Excitation of the [Re] center results in the population
of a diimine-based metal-to-ligand charge transfer excited state.
Reductive quenching by NEt3 produces the radically reduced
form of [Re], [Re]− (kq = 1.4 ± 0.1 × 107 M–1 s–1). Once formed, [Re]− reduces the
[NiFe2] center to [NiFe2]−, and this reduction was followed using time-resolved infrared spectroscopy.
The concentration dependence of the electron transfer rate constants
suggests that both inter- and intramolecular electron transfer pathways
are involved, and the rate constants for these processes have been
estimated (kinter = 5.9 ± 0.7 ×
108 M–1 s–1, kintra = 1.5 ± 0.1 × 105 s–1). For the analogous bimolecular system, only
intermolecular electron transfer could be observed (kinter = 3.8 ± 0.5 × 109 M–1 s–1). Fourier transform infrared spectroscopic
studies confirms that decomposition of the dyad occurs upon prolonged
photolysis, and this appears to be a major factor for the low activity
of the system toward H2 production in acidic conditions. Excitation of the [Re] center in the linked-dyad complex
([Re]-[NiFe2]) populates the 3MLCT excited state,
and reductive quenching by NEt3 produces [Re]−. [Re]− reduces the [NiFe2] center to
[NiFe2]− via inter- and intramolecular
electron transfer pathways (kinter = 5.9
± 0.7 × 108 M−1 s−1, kintra = 1.5 ± 0.1 × 105 s−1). For the analogous bimolecular system,
where only intermolecular electron transfer could be observed, kinter = 3.8 ± 0.5 × 109 M−1 s−1.

Abstract
A number of ruthenium(II) and rhenium(I) bipyridine complexes functionalized with lipoic acid moieties have been synthesized and characterized. Functionalization of gold nanoparticles with these chromophoric ruthenium(II) and rhenium(I) complexes has resulted in interesting supramolecular assemblies with Förster resonance energy transfer (FRET) properties that could be modulated via esterase hydrolysis. The luminescence of the metal complex chromophores was turned on upon cleavage of the ester bond linkage by esterase to reduce the efficiency of FRET quenching. The prepared nanoassembly conjugates have been characterized by transmission electron microscopy (TEM), energy-dispersive X-ray analysis (EDX), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), UV-visible spectroscopy, and emission spectroscopy. The quenching mechanism has also been studied by transient absorption and time-resolved emission decay measurements. The FRET efficiencies were found to vary with the nature of the chromophores and the length of the spacer between the donor (transition metal complexes) and the acceptor (gold nanoparticles).
