چکیده
A porphyrin derivative functionalized with the L-enantiomer of proline amino acid was characterized at air–pure water interface Langmuir trough. The dissolved in dichloromethane solution, spread air–subphase and investigated by acquiring surface pressure vs. area per molecule curves. It is worth observing that behavior molecules floating film substantially influenced presence L-proline subphase (10?5 M); on contrary, physical chemical features were only slightly D-proline subphase. Such an interesting chirality-driven selection preserved when transferred onto solid supports means Langmuir–Schaefer method, but it did not emerge a spin-coating technique used for layering tetrapyrrolic derivatives. obtained results represent proof concept realization active molecular layers chiral discrimination: derivatives, due to their intriguing spectroscopic supramolecular properties, can be should detected. Moreover, emphasize crucial role deposition sensing layers.

The distribution behavior of ofloxacin enantiomers was examined in the aqueous and organic solvent of a two-phase system containing chiral selector L-tartarate. The effect of extraction equilibrium time, buffer pH, organic solvents and length of alkyl chain of L-tartarate on the partition coefficients and enantioselectivity of racemic ofloxacin were investigated, respectively. The L-tartara...

Alginate-metal complexes were prepared with divalent (Ca, Ba, Zn) and trivalent metals (Fe, Al) via congealing method in form of beads. Alginate mixed metals (Ca & Fe) complexes were also prepared by simultaneous and consecutive congealing. The studied beads were blank beads and racemic ketoprofen (KTP) loaded beads. Metal content was determined by atomic absorption spectroscopy and was 1.8% to...

We report on the Langmuir-Blodgett film formation and properties of a ruthenium porphyrin complex. Multilayer films may be transferred onto a variety of substrates. Reproducible deposition is indicated by both optical and electrical measurements. Ellipsometry reveals the thickness per layer to be 1.65 k 0.05 nm. A marked increase in the in-plane electrical conductivity of these layers is found ...
