Polymerization of new aniline derivatives: synthesis, characterization and application as sensors.

This work is focused on modifying aniline monomers with various characteristics that allows one to study the effect of the substituent on the respective polymer. A series of new polyaniline (PANI) derivatives based on an -substituted aniline derivative, 2-(1-methylbut-2-en-1-yl)aniline, were synthesized and characterized. The structures and composition of the polymers that we synthesized were confirmed by elemental analysis, proton nuclear magnetic resonance (H NMR) spectroscopy, carbon nuclear magnetic resonance (C NMR) spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), and ultraviolet-visible spectroscopy (UV).

Photoconductivity of Thin Films Obtained from a New Type of Polyindole.

The optoelectronic properties of a new poly(2-ethyl-3-methylindole) (MPIn) are discussed in this paper. The absorption and photoluminescence spectra were studied. The electronic spectrum of MPIn showed a single absorption maximum at 269 nm that is characteristic of the entire series of polyindoles.

Effect of structural factors on the physicochemical properties of functionalized polyanilines.

This review discusses the physical and physicochemical properties of polyaniline (PANI) derivatives. The most important methods for the preparation of functionalized polyanilines are presented. The presence of various substituents in its structure changes the polymer characteristics significantly due to steric and electronic effects of the functional groups.

[Single-centre experience with implantation of the 'E-vita open plus' hybrid stent graft].

Hybrid technologies appear to have been gaining ground in surgery of the thoracic aorta. The present study was aimed at assessing the immediate clinical outcomes of surgical treatment of diseases of the thoracic aorta by means of the 'E-vita open plus' hybrid stent graft. The 'E-vita open plus' hybrid stent graft was implanted to 18 patients.
