Метельский, А. В. (1994)

Spectroscopy of interchromophoric interactions in self-organized porphyrin and chlorin complexes

Zenkevich, E. I.; Shulga, A. M.; Chernook, A. V.; Rempel, U.; von Borczyskowski, C. (1995)

Spectral-luminescent properties of multimolecular complexes (triads and pentads, complexation constants range from 5∙10⁶ to 5∙10⁷ M⁻¹) formed by two-fold coordination of dipyridyl and tetra-pyridyl substituted porphyrin ...

Investigations of Chl α aggregates cross-linked by dioxane in 3-methylpentane

Oksanen, J. A. I.; Zenkevich, E. I.; Knyukshto, V. N.; Pakalnis, S.; Hynninen, P. H.; Korrpi-Tommola, J. E. I. (1997)

In this work, dioxane-bound aggregates of chlorophyll a are prepared in 3-methylpentane. The properties of the aggregates are studied by using steady-state and time-resolved spectroscopies. The Qy-region absorption spectrum ...

Complexation and interchromophoric interactions in self-organized porphyrin and chlorin triads

Chernook, A. V.; Shulga, A. M.; Zenkevich, E. I.; Rempel, U.; von Borczyskowski, C. (1996)

Spectral properties and equilibrium constants of multimolecular complexes (triads) formed by 2-fold coordination of dipyridyl-substituted free bases of porphyrin, chlorin, or tetrahydroporphyrin with Zn-porphyrin and ...

Electron transfer in porphyrin multimolecular self-organized nanostructures

Zenkevich, E. I.; Bachilo, S. M.; Shulga, A. M.; Rempel, U.; Willert, A.; von Borczyskowski, C. (1998)

On the base of of covalent and non-covalent bonds nanoscale self-assembling multiporphyrin arrays with well-defined geometry, the controllable number of interacting components and their spectral and photophysical properties ...

Resonance Raman spectra interpretation by molecular coherent state representation

Trifonov, N. Yu. (1992)

In this paper the problem of exact summation over vibrational states of intermediate electronic level excited by resonance Raman scattering in a molecular system with an arbitrary number of vibrational modes is solved with ...

Fluorescence line narrowing study of cyclopentaneporphyrin chemical dimers at 4.2 K

Starukhin, A.; Zenkevich, E. I.; Shulga, A.; Chernook, A. (1996)

The monomers of Zn-cyclopentanporphyrins (ZnOEP-cycle and ZnOEP-cycle=CH2) and their chemical dimers covalently linked via isocycles (Zn-cyclodimers) have been studied by the method of fluorescence line narrowing (FLN) in ...

Pathways for photoinduced electron transfer in meso-nitro-phenyl-octaethylporphyrins and their chemical dimers

Knyukshto, V.; Zenkevich, E.; Sagun, E.; Shulga, A.; Bachilo, S. (1999)

The photophysical properties of meso-nitro-phenyl-octaethylporphyrins and their dimers with electron-accepting NO₂ groups in the para-, meta- and ortho-positions of the phenyl ring were studied. For the ortho-NO₂ case in ...

Energy transfer in ethane-bisporphyrins studied by fluorescence line narrowing and spectral hole burning

Mauring, K.; Suisalu, A.; Kikas, J.; Zenkevich, E. I.; Chernook, A. V.; Shulga, A. M.; Gurinovich, G. P. (1995)

The quasi-line fluorescence excitation spectrum of 1,2-bis (2,3,7,8,12,13,17,18-octaethyl-21H,23 H-porphino) ethane at 4.8 K consists of two subbands with the splitting mean value of 51cm⁻¹, that are ascribed to the donor ...

Formation and optical properties of self-organized pentameric porphyrin arrays

Chernook, A. V.; Rempel, U.; von Borczyskowski, C.; Zenkevich, E. I.; Shulga, A. (1996)

Principles of formation, electronic absorption and fluorescence spectra are reported for self-organized pentameric arrays of tetrapyrrolic macrocycles. In these arrays two molecules of Zn-porphyrin dimers, Zn(II)l,4-bis[ ...
