[en] The characteristic features of the structures and properties of crown-substituted porphyrinates and phthalocyaninates are considered. Interactions of these compounds with alkali metal salts yield supramolecular ensembles. The factors determining the architecture of such ensembles are described.
[en] The properties of solutions of alkali metals in amine solvents were studied by optical, ETR, NMR and electrochemical methods. Complexation of the alkali cations by crown ethers and cryptands permitted the preparation of concentrated solutions of alkali metals in amine and ether solvents. Extensive alkali metal NMR studies of the exchange of M+ with crown-ethers and cryptands and of the alkali metal anion, M-, were made. The first crystalline salt of an alkali metal anion, Na+ Cryptand [2.2.2]Na- was synthesized and characterized and led to the preparation of other alkali metal anion salts. This research provided the foundation for continuing studies of crystalline alkalide salts
[en] Small clusters made up of three kinds of neutral alkali atoms, i.e. clusters of the form XlYmZn, are theoretically studied. These clusters exhibit three series of magic numbers, one for each kind of atoms. That is, l, m, and n independently can be magic numbers rather than their cumulative number l+m+n or, in other words, magic numbers in alkali clusters composed of neutral atoms are due to atoms rather than to delocalized electrons as in jellium model. Of course, if conditions favor delocalization of electrons, l+m+n can be magic but then we have no neutral atoms which are prerequisite for an application of the present model. (orig.)
[en] Differential equation for describing diffusion in near-electrode areas in melts with partially electron conductivity is deduced. Equation solutions for cases of stationary polarization, chronopotentiometry and reversible chronopotentiometry with switching over from stationary state are found
