Rhenium complexes of 5,10,15,20-tetraphenylporphine, 5,10,15,20-tetrakis(4-methoxyphenyl)porphyrin, 5,10,15,20-tetrakis(4-methoxycarbonylphenyl)porphyrin, and 2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetraphenylporphyrin were synthesized and characterized by mass spectrometry, electron and 1H NMR spectroscopy, and HPLC. The X-ray photoelectron spectra of the complexes showed that rhenium is present predominantly in the pentavalent state. The optimized geometries, dipole moments, and charge and spin density distributions of the synthesized complexes were obtained by quantum-chemical calculations, as well as Mulliken population analysis was performed.

We study the density-matrix kinetics of a charged test particle in two types of Coulomb environment. For a prescribed Gaussian potential, averaging the random-unitary dynamics leads to a Born–Novikov memory equation; Novikov’s identity is exact, but its closure requires a second-order approximation. An equilibrium quantum bath instead yields a Born–Redfield equation with ordered correlators and ...

In this paper, we study a new class of wave solutions to the SU(2) Yang-Mills equations in the
region outside field sources. They represent a significant addition to the wave solutions obtained
in our previous publications describing non-Abelian transverse progressive waves propagating
in the direction of the Cartesian z-axis. In the new paper, wave solutions to the considered
system ...

We study coherent electric manipulation of magnetic field induced localized states at a double kink of a helical edge in a HgTe/CdHgTe quantum well. An in-plane magnetic field opens a gap in the one-dimensional (1D) edge spectrum, while changes in the edge orientation generate localized in-gap states at the kinks. We show that, for suitable ...

We derive the local pressure tensor generated by the original Rosenfeld fundamental measure theory (FMT) for hard-sphere fluids from an arbitrary infinitesimal deformation. The variation of a finite-distance FMT kernel is written via the line integrals of the local deformation gradient along the straight segment connecting its end points. The resulting symmetric pressure tensor consists ...

A series of new coumarin-azine fluorophores based on 1,2,4-triazinyl and pyridinyl substituted derivatives of 7-aminocoumarin was synthesized via a nucleophilic substitution of hydrogen (SNH) reaction followed by an inverse electron-demand Diels–Alder transformation. The primary photophysical properties of 3-triazinyl coumarins and their pyridine analogs was investigated in toluene and acetonitrile solutions. Thus, the emission of the fluorophores in ...

Задача о возбуждении бегущих фонон-поляритонных волн на поверхности полярного кристалла падающей извне световой волной (с частотой, близкой к частоте решеточных колебаний) решена теоретически только для бесконечной открытой поверхности кристалла. В случаях, когда часть поверхности покрыта металлической маской, препятствующей проникновению возбуждающего излучения к атомам среды, и эта маска имеет произвольную форму, общепризнанного решения неоднородной задачи нет. ...

Conformational space of polyphenylenevinylene oligomers is systematically investigated computationally at energies relevant for room temperature dynamics in a solvent and in a solid state. Our calculations show that optimal oligomer structures are essentially planar. However, lack of a deep minimum at the planar geometry allows for large molecular deformations even at very low temperatures. At ...

The complexation of high-spin lanthanides to porphyrinoids is a powerful strategy for the development of advanced molecular magnets. In this context, the use of expanded porphyrinoids remains elusive since their coordination chemistry is challenging to control. Herein, taking inspiration from on-surface chemistry, we explored the coordination of Dy3+ to a six-membered porphyrinoid, namely, the hemihexaphyrazine ...

Macromolecular porphyrin nanorings are receiving significant attention because of their excellent optoelectronic properties. However, their efficiencies as potential solar materials are significantly affected by nonradiative charge recombination. To understand the recombination mechanism by alternating structural parameters and using tight-binding nonadiabatic molecular dynamics, we demonstrate that charge recombination depends strongly on the mode of the linker ...
