Enzyme modified electrodes were fabricated with poly(aniline-co-maminophenol). Electrochemical polymerization of aniline and m-aminophenol was performed to get the film of copolymer on the surface of gold electrode. Modified electrodes were fabricated by two methods, physical entrapment and covalent cross-linking. In one of the method, gold nanoparticles were loaded into the copolymer film and ...

Novel red and purple reactive disperse silicon-containing dyes were designed and synthesized using p-nitroaniline and 6-bromo-2,4-dinitro-aniline as diazonium components, the first condensation product of cyanuric chloride and 3-(N,N-diethyl)amino-aniline as coupling component, and 3-aminopropylmethoxydimethylsilane, 3-aminopropylmethyldimethoxysilane, and 3-aminopropyltrimethoxysilane as silic...

In the title compound, C11H10INO3, an addition product of itaconic acid anhydride and 4-iodo-aniline, the least-squares planes defined by the atoms of the aromatic moiety and the non-H atoms of the carb-oxy-lic acid group enclose an angle of 74.82 (11)°. In the crystal, classical O-H⋯O hydrogen bonds formed by carb-oxy-lic groups, as well as N-H⋯O hydrogen bonds formed by amide groups, are pres...

In the title compound, C(26)H(25)NO(6), the anthraquinone ring system forms a dihedral angle of 15.5 (1)° with the benzene ring of the dimethyl-aniline group. Intra-molecular O-H⋯O hydrogen bonding is observed between the carbonyl and two hydroxyl groups. The mol-ecules are linked into a ribbon-like structure along the [100] direction by O-H⋯N and C-H⋯O hydrogen bonds. The crystal used was twin...

Well-defined voltammetric current peaks of polyaniline were observed at biosensors hybridized with ruthenium oxide nanoparticle-tagged microRNAs and incubated in a mixture of aniline/H(2)O(2), which can be used for direct microRNA expression profiling with excellent sensitivity.

The title compound, C(13)H(10)BrNO, was prepared by reaction of 3-bromo-aniline with 2-hydroxy-benzaldehyde at 377 K. The mol-ecular structure and packing are stabilized by an intra-molecular O-H⋯N hydrogen-bond inter-action.
