Tlenek cynku jest obiecującym materiałem do budowy anod ze względu na możliwość uzyskiwania go w postaci różnych nanostruktur oraz doskonałą ruchliwość elektronów. W celu poprawy działania ogniw fotowoltaicznych otrzymano nanostruktury ZnO i zastosowano je w elektrodach półprzewodnikowych. Jako podłoże warstwy ZnO zastosowano szkło z tlenku cyny domieszkowanego fluorem FTO (fluorine-doped tin oxide). Po wyżarzaniu pokryto je warstwą składającą się z mikrokulek polistyrenowych wytworzonych in situ metodą polimeryzacji wolnorodnikowej. Zarodki ZnO hodowano w mieszaninie azotanu cynku i heksametylenotetraaminy w celu wytworzenia różnych typów nanostruktur ZnO (struktura siatki 3D i struktura nanodrutu-nanocząstki) o dużej powierzchni właściwej. Warstwę kompozytową uczulono barwnikiem N719 i zastosowano w ogniwach słonecznych. Uzyskano efektywność konwersji energii 3,91%.

ZnO was deposited from Zn(OAc)2 soln. on F-doped SnO glass substrate by spin coating. After the procedure was repeated 4 times, the layer was annealed at 400°C for 1 h and covered with template layer consisting of polystyrene microspheres in-situ produced by free radical emulsion polymerization. The seed layer was grown in the mixt. of Zn(NO3)2 and hexamethylenetetramine to produce ZnO of nanowire-nanoparticle structures with high sp. surface area. The template layer was then removed by heating at 500°C for 1 h under formation of ZnO nanostructures. Di(tetrabutylammonium)cis-bis(isothiocyanato)bis(2,2’- bipyridyl-4,4’-dicarboxylato)ruthenium(II) (N719 dye) was then deposited from its soln. on the composite surface and sensitized in dark for 1 h. The product was characterized by X-ray diffractometry, elec. impedance spectroscopy and scanning electron microscopy and then successfully used as a semiconductor electrode in a solar cell of improved performance.

Metal-organic frameworks (MOFs) are a class of porous hybrid materials comprising metal ion-based vertices and multitopic organic ligands (linkers). The possibility of combining a wide range of metals with similarly large number of available ligands opens ways to design the structures meeting specific purposes. At present, many potential applications of MOFs may require them to be constructed at the nanometer length scale (nanoMOFs). The possibility of filling the track-etched membrane pores with MOF HKUST-1 has been demonstrated in this work.

A new series of 14-membered macrocyclic complexes containing nitrogen and sulfur donor atoms have been synthesized by metal template condensation reactions of 1,2-ethane -dithiol, omikron-bromoaniline and succinic or phthalic acid in 1:2:1 molar ratio in metha nol. The proposed stoichiometry and the bonding of the macrocyclic moiety to metal ions along with the over all stereochemistry have been derived from the results of elemental analyses, magnetic susceptibility, conductivity data and the spectral data revealed from FT-IR, 1H NMR, UV-visible and EPR spectral studies. The molar conductance measurements of the complexes in DMSO correspond to be none-electrolyte nature for Co(II) and Zn(II) while 1:2 electrolyte for Ni(II) and Cu(II) complexes. Thus, these complexes may be formulated as [ML1X2] and [ML2X2] (M = Co(II), or Zn(II); X = Cl or NO3), and [ML1]X2 and [ML2]X2 (M = Ni(II) or Cu(II); X = Cl or NO3). On the basis of IR, electronic and EPR spectral studies an octahedral geometry has been as signed for Co(II) and Zn(II) complexes while square-planarfor Ni(II) and Cu(II) complexes.

Lanthanum(III) chloride and nitrate appear to be effective template agents in the one-step synthesis of salicylaldimine complexes derived from salicylaldehyde and biogenic diamines putrescine or cadaverine. The potentially tetradentate N2O2 Schiff bases display a rare coordination pattern of salen-type complexes acting as neutral ligands us ing oxygens as do nor atoms with out in volving the nitrogen atoms in the coordination. The synthesis and characteriz tion of the new free salicylaldimine ligand derived from cadaverine was also carried out.

Template condensation of the metal ions with hydrazine, 2,4-pentanedione and acetaldehyde in a 1:4:2:2 molar ratio resulted in the formation of a new series of 16-membered octaazamacrocyclic complexes: dichloro/nitrato [2,5,8,10,13,16-hexamethyl-3,4,6,7,11, 12,14,15-octaazacyclohexadecane-2,7,10,15-tetraene)metal(II)], [MLX2] (M = Fe(II), Co(II), Ni(II), Cu(II) and Zn(II); X = Cl or NO3). The overall geometry and stereochemistry of the complexes have been characterized by elemental analyses, IR, 1HNMR, EPR, UVvisible, magnetic susceptibility and conductivity measurements. An octahedral geometry is suggested for all of the complexes. The conductivity data suggest that the complexes are non-ionic in nature.

The template reaction of 2,6-diacetylpyridine with putrescine, a biogenic diamine, in the presence of lanthanum(III) and zinc(II) ions produces homo- and heteronuclear complexes of 22-membered macrocyclic ligand with an N6 set of donor atoms as a result of the [2+2] Schiff base cyclocondensation. Complexes containing Schiff base acyclic ligands terminated by two carbonyl groups or one carbonyl and one amine group as products of the partial metal-promoted condensation have been also isolated. They might be regarded as possible intermediates in the formation of the macrocyclic complexes. The complexes have been characterized by spectral data (IR, 1H NMR, ESI-MS) and elemental analyses.

Homodinuclear complexes with magnesium(II), calcium(II), and barium(II) ions and heterodinuclear complexes with calcium(II) or cadmium(II) and lanthanide(III) ions containing Schiff base open-chain ligand terminated by one amine and one carbonyl group were prepared as a result of the partial Schiff base condensation reaction between 2,6-diacetylpyridine and 4-methyl-1,2-phenylenediamine in the presence of the appropriate ions acting as templates. The complexes were characterized by spectroscopic methods (IR, 1H NMR, FAB-MS), thermogravimetric and elemental analyses.
