Abstract
Novel dual-responsive macromolecular ligands for metal coordination were developed, for which the aggregation state is affected by the two stimuli of temperature and Fe2+ ions.

Abstract
AbstractBased on readily available N-(2,2,2-trichloro-1-hydroxyethyl)carboxamides, N-(2,2,2-trichloro-1-(3-(3-mercapto-4H-1,2,4-triazol-4-yl)thioureido)ethyl) carboxamides, dehydrosulfurization–under the influence of excess HgO–led to the formation of N-(1-([1,2,4] triazolo[3,4-b][1,3,4]thiadiazol-6-ylamino)-2,2,2-trichloroethyl)carboxamides. The reaction was carried out in boiling glacial acetic acid for 1-1.5 hours. The cyclization products were obtained in 42-62% yields and easily isolated from the reaction mixture. The structure of all synthesized compounds was confirmed by complex spectral studies.

Abstract
This paper describes the synthesis, spectroscopic characterization and quantum mechanical calculations of three azo-azomethine dyes. The dyes were synthesized via condensation reaction between 4-(dimethylamino)benzaldehyde and three different 4-aminobenzene azo dyes. Quantum chemical calculations on the optimized molecular geometry and electron densities of the trans (E) and cis (Z) isomers and their vibrational frequencies have been computed by using DFT/B3LYP density-functional theory with 6-311++G(d,p) basis set in vacuo. The thermodynamic parameters such as total electronic energy E (RB3LYP), enthalpy H298 (sum of electronic and thermal enthalpies), free Gibbs energy G298 (sum of electronic and thermal free Gibbs energies) and dipole moment μ were computed for trans (E) and cis (Z) isomers in order to estimate the ΔEtrans→cis, Δμtrans→cis,ΔHtrans→cis, ΔGtrans→cis and ΔStrans→cis values. After molecular geometry optimization the electronic spectra have been obtained by TD-DFT calculations at same basis set and correlated with the spectra of vapour deposited nanosized films of the dyes. The NBO analysis was performed in order to understand the intramolecular charge transfer and energy of resonance stabilization. Solvatochromism was investigated by UV-VIS spectroscopy in five different organic solvents with increasing polarity. The dynamic photoisomerization experiments have been performed in DMF by pump lasers λ=355nm (mostly E→Z) and λ=491nm (mostly Z→E) in spectral region 300nm - 800nm at equal concentrations and times of illumination in order to investigate the photodynamical trans-cis-trans properties of the CHN and NN chromophore groups of the dyes.
