The effect of three aromatic amines namely aniline (AN), dimethyl aniline (DMAN) and diethyl aniline (DEAN) on emission properties of a coumarin derivative 6-methyl-3azidoacetyl coumarin (6M3AAC) in acetonitrile was studied by means of steady state fluorescence spectroscopy. The quenching of fluorescence intensity was observed in the presence of amines. The quenching process was characterized b...

Singlet Oxygen, Radicals, Fluorescein, Diphenylisobenzofuran, Reversed Micelles The 1,3-diphenylisobenzofuran oxidation reaction was investigated in methanolic and dodecylammonium propionate reversed micellar solutions using fluorescein sodium as photosensitizer. It was found that aniline remarkably enhanced the furan oxidation in methanolic solutions but inhibited it in reversed micellar solut...

Experimental Reagents. 3-aminophenylboronic acid (ABA), Nafion (40 wt% alcohol-water mixed solution), sodium fluoride, D-glucose (GL), fructose (FR), and α-methyl-D-glucoside were purchased from Aldrich and used as purchased. Phosphate buffer saline (PBS) stock solution, pH 7.4, (x10 concentrated stock) was purchased from EM Science. The water that was used for all experiments was purified and ...

Aniline is a toxic organic pollutant and raw material in industries. In this study, the start-up of sequencing batch reactor for treating aniline wastewater was assessed functional microbial clusters were analyzed after enrichment denitrifying phosphate-accumulating organisms (DNPAOs). The degradation subsequent removal NH4+-N mainly happened aerobic condition, denitrification conducted both an...

This work describes the fabrication of poly(4-styrenesulfonic acid)-doped polyaniline/graphene (PSS-doped PANI/graphene) nanocomposites and their use as sensing elements for hydrogen sulfide (H2S) detection. PSS with a weight-average molecular weight (Mw) of 1.96 × 10(6) was synthesized using low-temperature free-radical polymerization. The PSS was used as both a doping agent and a binding agen...

In the title compound, [CuCl(2)(C(6)H(7)N)(2)(C(12)H(8)N(4)O)](n), the Cu atom, located on an inversion center, is coordinated by four N atoms from two aniline ligands and two 2,5-bis-(4-pyrid-yl)-1,3,4-oxadiazole ligands. Two Cl atoms lying above and below the plane formed by these four N atoms inter-act weakly with the Cu atom [Cu-Cl = 2.7870 (7) Å]. The trans 2,5-bis-(4-pyrid-yl)-1,3,4-oxadi...

In the structure of the the title compound, C(13)H(9)Cl(2)NO, the N-H and C=O groups are mutually trans. Furthermore, the conformation of the C=O group is syn to the ortho-chloro group in the benzoyl ring, while the N-H bond is anti to the meta-chloro group in the aniline ring. The amide group forms dihedral angles of 89.11 (19) and 22.58 (37)°, respectively, with the benzoyl and aniline rings,...

A gold(I)-catalyzed 6-endo-dig cyclization of aromatic 1,5-enyne was developed to synthesize 2-(naphthalen-2-yl)aniline. The functional group tolerance this examined systematically and a possible mechanism proposed. derivatization 2-(naphthalen-2-yl)aniline carried out facile access benzo[α]carbazole, benzo[c,h]cinnoline dibenzo[i]phenanthridine derivatives in divergent way.
