Restricted chain rotation in polymers containing pendant groups: structural characterization of hydroxyl-functionalized polysulfones

Synthesis and Characterization of Polyamide Containing Maleimide Pendant Group

A series of new polyamides containing maleimide pendant group were prepared by low temperature polycondensation of 5-(4-(2,5-dioxo-2H-pyrrol-1(5H)-yl)benzamido)isophthaloyl chloride as a new monomer with various aromatic diamines in NMP. Monomer and polymers structures were identified through FT-IR, 1H-NMR and elemental analysis. Obtained polymers were soluble in polar solvents and non solu...

Near-Infrared Electrochromic and Electroluminescent Polymers Containing Pendant Ruthenium Complex Groups

A series of near-infrared (NIR) electrochromic and electroluminescent polymers containing the pendant dinuclear ruthenium complexes were synthesized and characterized. All the polymers are near-infrared (NIR) electrochromic, displaying an intense absorption centered at 1600 nm upon oxidation to the mixed-valence state. Single-layer diode devices comprising a layer of the complex polymers sandwi...

Ring Rotation in Ferrocene and Ferrocene-containing Polymers

Ferrocene is an organometallic molecular sandwich complex with an iron atom coordinated between two cyclopentadienyl rings. The reorientation of these rings in a process of rotational jump diffusion between multiple equilibrium sites on a circle is investigated using quasielastic neutron time of flight and backscattering spectroscopy experiments. Existing results on the ring rotation in bulk, c...

Mild and Solvent-free Synthesis and Antibacterial Evaluation of Novel Sulfonamides Containing Hydroxyl Groups

A series of interesting sulfonamides containing hydroxyl group were synthesized under solvent-free conditions. The synthetic route involves the selective reaction of amino alcohol and sulfonating agents. The sulfonamides were obtained by simple procedure after an easy work-up in high yield and purity, and characterized by IR, 1H NMR and 13C NMR analysis. These compounds were tested for antibact...
