Infrared spectroscopy of gas-phase Cr+ complexes of aniline was studied using the FELIX free electron laser interfaced to a Fourier transform ion cyclotron resonance spectrometer. For both the monomer complex Cr+(aniline) and the dimer complex Cr+(aniline)2 the spectra showed features indicating binding of the metal ion to the aromatic pi cloud, as opposed to the nitrogen atom. Agreement with D...

The asymmetric unit of the title complex, (C(6)H(8)N)(2)[Cu(C(7)H(3)NO(4))(2)]·6H(2)O, contains half a copper(II)-dipicolinate complex located on a twofold rotation axis, one protonated aniline mol-ecule and three solvent water mol-ecules. The Cu(II) atom is coordinated by four O atoms and two N atoms from two dipicolinate ligands in a distorted octa-hedral environment. In the crystal, the comp...

An electrochemical study of two water-soluble aniline derivatives, N-(3-sulfopropyl) aniline (AnPS) and N-(3-sulfopropyl) p-aminodiphenylamine (DAnPS), in aqueous acidic electrolytic solutions containing different kinds of doping anions (Cl (-), SO(4) (2-), and ClO(4) (-)) was carried out. At sufficiently high anodic potential, the sulfonated aniline derivatives undergo oxidation processes yiel...

Hydrolysis of D-valyl-L-leucyl-L-arginine p-nitroanilide (7.5-90.0 microM) by human tissue kallikrein (hK1) (4.58-5.27 nM) at pH 9.0 and 37 degrees C was studied in the absence and in the presence of increasing concentrations of 4-aminobenzamidine (96-576 microM), benzamidine (1.27-7.62 mM), 4-nitroaniline (16.5-66 microM) and aniline (20-50 mM). The kinetic parameters determined in the absence...

Aniline-terminated self-assembled monolayers (SAMs) on gold surfaces have successfully reacted with ArSO2NHOSO2Ar (Ar = 4-MeC6H4 or 4-FC6H4) resulting in monolayers with sulfamide moieties and different end groups. Moreover, the sulfamide groups on the SAMs can be hydrolyzed showing the partial regeneration of the aniline surface. SAMs were characterized by water contact angle (WCA) measurement...

An ion imprinted polymer (IIP) based on aniline-formaldehyde was synthesized and then modified with extra aniline as cross-linker in the presence and absence of Sr (II) as the template to produce ion imprinted poly(aniline-formaldehyde) (IIPAF) and non imprinted poly(aniline-formaldehyde) (NIPAF). The sorbent was characterized by Fourier Transform Infrared Spectroscopy and was used for solid ph...
