    • 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 tetrahydrofurane-toluene (3:1) glassy matrixes at 4.2 K. Well-resolved fluorescence spectra upon laser excitation into the S₀→S₁ absorption band have been ...

    • Temperature dependent steric hindrance effects in triplet state relaxation of meso-phenyl-substituted Pd-octaethylporphyrins 

      Gorski, A.; Knyukshto, V.; Zenkevich, E.; Starukhin, A.; Kijak, M.; Solarski, J.; Semeikin, A.; Lyubimova, T. (Elsevier, 2018)
      The analysis of spectral-kinetic results of transient absorption and phosphorescence experiments has been carried out in a wide temperature range (80-293K) for a series of Pd-octaethylporphyrin derivatives (PdOEP) with increasing number of bulky meso-phenyl substituents. In order to elucidate the influence of steric hindrance interactions, as well as porphyrin macrocycle non-planarity ...
