Axial Coordinated Manganese(III) Porphyrin/Tetraazaporphyrin - 4-(10-phenylanthracen-9-yl)Pyridine Dyads: Self-Assembly, Structure and Spectral Properties in Ground and Excited States.

Self-assembly of new donor-acceptor systems based on (5,10,15,20-tetraphenylporphinato)manganese(III)/(5,10,15,20-tetra-4-tert-butylphenylporphinato)manganese(III)/(octakis(4-tert-butylphenyl)tetraazaporphinato)manganese(III) acetate ((AcO)MnTPP/(AcO)MnTBPP/(AcO)MnTAP) and 4-(10-phenylanthracen-9-yl)pyridine (PyAn) was studied using fluorescence spectroscopy and mass spectrometry. It was found that the coordination complexes of 1 : 1 composition (dyads) are formed in toluene. The spectral properties, the chemical structures and redox behavior of the dyads were described using H NMR, IR, ESR spectroscopy and cyclic voltammetry, respectively.

Donor-Acceptor Complexes of (5,10,15,20-Tetra(4-methylphenyl)porphyrinato)cobalt(II) with Fullerenes C: Self-Assembly, Spectral, Electrochemical and Photophysical Properties.

The noncovalent interactions of (5,10,15,20-tetra(4-methylphenyl)porphinato)cobalt(II) (CoTTP) with C and 1-N-methyl-2-(pyridin-4-yl)-3,4-fullero[60]pyrrolidine (PyC) were studied in toluene using absorption and fluorescence titration methods. The self-assembly in the 2:1 complexes (the triads) (C)CoTTP and (PyC)CoTTP was established. The bonding constants for (C)CoTTP and (PyC)CoTTP are defined to be (3.

N Basicity of Substituted Fullero[60]/[70]pyrrolidines According to DFT/TD-DFT Calculations and Chemical Thermodynamics.

The basicity thermodynamic parameters of pyridyl/imidazole-substituted fullero[60]/[70]pyrrolidines with respect to N heteroatoms in dichloromethane, which are necessary both to deepen insight into aromaticity "neque levia" and to create supramolecular chemical structures for application, are obtained and discussed in this work. Because of the presence of a chromophore in the molecules, the acid-base reactions of three C derivatives functionalized in different ways and one C derivative are studied using spectrophotometric titration with trifluoroacetic acid. The dependence of the p values determined using the data on Hammett's acidity functions, , for a binary nonaqueous solvent on the molecule's chemical structure is shown.
