Abstract
Reaction of (2,3,9,10,16,17,23,24-octabutylphthalocyaninato)lanthanide(iii) acetylacetonates (BuPcLn(acac), 1a-c, Ln = Lu (a), Eu (b), La (c)) with a tetrakis(5,7-bis(4-tert-butylphenyl)-6H-1,4-diazepino)[2,3-b,g,l,q]porphyrazine ligand (tBuPhDzPzH2, 2) produced sandwich compounds (tBuPhDzPz)Ln(BuPc) (3a-c), which represent the first heteroleptic double-deckers incorporating both Pc and DzPz decks. A combination of high-resolution mass spectrometry, UV-Vis/NIR, MCD, and 1H NMR spectroscopy, and square-wave voltammetry provided unambiguous characterization of target complexes 3 indicating that their spectral and electrochemical properties are generally intermediate with respect to their homoleptic relatives. Based on the data of solution-state 1H-1H NMR (COSY, NOESY) correlation spectroscopy supported by DFT calculations, a dimerization tendency of compounds 3 proportional to the Ln(iii) ion size was found. The spectroelectrochemical study of 3 and the corresponding homoleptic double-deckers revealed a pronounced tendency to aggregation of the one-electron oxidized forms of DzPz-containing double-decker complexes compared to homoleptic Pc2Ln compounds.

Abstract
5,7-Substituted 1,4-diazepinoporphyrazine magnesium(ii) complexes were synthesized via Mg(ii)-alkoxide templated macrocyclization. A single crystal growth synchrotron diffraction analysis permitted what is to our knowledge the first structural characterization of a 1,4-diazepinoporphyrazine. It exists as a dimer in the solid state. In silico calculations supported by solution phase spectral studies involving a series of representative derivatives, provided insights into the factors governing dimerization of 1,4-diazepinoporphyrazines. The present 1,4-diazepinoporphyrazines serve as useful probes for understanding the determinants that guide dimer-monomer equilibria and the self-assembly of phthalocyanine derivatives.

Abstract
The electrochemical and spectroelectrochemical behavior of two planar binuclear naphthalocyanines containing benzene and naphthalene π-conjugated bridges was investigated for the first time. Their intense absorption in the near infrared region was observed even in a low polar solvent such as o-dichlorobenzene after electrochemical reduction at a potential of -0.4 V vs. SCE, which was not enough to reduce the complexes into their first reduction state. These data and EPR studies allow us to conclude that the electrochemically generated form is the true neutral form of the synthesized compounds whereas the suppression of the near-infrared bands is a result of the presence of their cation radicals as one-electron oxidized forms.

Abstract
Methylamine dehydrogenase (MADH) and azurin were purified from the periplasmic fraction of the methylamine-grown obligate methylotroph Methylobacillus flagellatus KT. The molecular mass of the purified azurin was 16.3 kDa, as measured by SDS–PAGE, or 13 920 Da as determined by MALDI–TOF mass spectrometry. Azurin of M. flagellatus KT contained 1 copper atom per molecule and had an absorption maximum at 620 nm in the oxidized state. The redox potential of azurin measured at pH 7.0 by square-wave voltammetry was +275 mV versus normal hydrogen electrode. MADH reduced azurin in the presence of methylamine, indicating that this cupredoxin is likely to be the physiological electron acceptor for MADH in the electron transport chain of the methylotroph. A scheme of electron transport functioning in M. flagellatus KТ during methylamine oxidation is proposed.

Abstract
A novel electrochemical approach for label-free detection of DNA primary sequence has been proposed. The flow of nonelectroactive ions across a liquid|liquid interface was used as an electrochemical probe for detection of DNA hybridization. Disposable graphite screen-printed electrodes shielded with a thin layer of inert polymer plasticized with water-immiscible polar organic solvent were modified by probe oligonucleotide and used as a DNA sensor. The specific DNA coupling has been detected with impedance spectroscopy by decrease of ion-transfer resistance. The detection limit was of 10-8 M of target oligonucleotide. The reported sensor was suitable for discrimination of a single mismatch oligonucleotide from the full complementary one. The reported DNA sensor was advantageous over known physicochemical approaches, providing the most significant changes in the measured parameters.
