Water-soluble carbon nanoparticles were prepared by refluxing natural gas soot in concentrated nitric acid. The surface of the resulting nanoparticles was found to be decorated with a variety of oxygenated species, as suggested by spectroscopic measurements. Back potentiometric titration of the nanoparticles was employed to quantify the coverage of carboxylic, lactonic, and phenolic moieties on...
متن کامل4,4′-Dibromo-2-nitrobiphenyl
The title compound, C(12)H(7)Br(2)NO(2), a biphenyl derivative, displays a twisted conformation with the two benzene rings making a dihedral angle of 55.34 (14)°. The dihedral angle between the nitro group and its parent benzene ring is 26.8 (2)°. The crystal structure is stabilized by inter-molecular C-H⋯Br and C-H⋯O inter-actions, which lead to the formation of chains propagating along the c-...
متن کامل9,9′-Dibromo-9,9′-bifluorene
9,9'-Dibromo-9,9'-bifluorene, C(26)H(16)Br(2), has a gauche conformation about the connecting C-C bond [the Br-C-C-Br torsion angle is 59.39 (16)°]. The crystal structure is sustained mainly by an inter-molecular C-Br⋯π inter-action [3.299 (2) and 3.369 (2) Å] towards the bifluorene aromatic-ring-connecting C-C bond and a weak C-H⋯π inter-action (2.86 and 2.99 Å) between the two aromatic rings.
متن کامل1,4-Dibromo-2,5-dibutoxybenzene
The asymmetric unit of the title compound, C(14)H(20)Br(2)O(2), contains one half-mol-ecule located on an inversion centre. The mol-ecule is essentially planar, with a maximum deviation from the best plane of the non-H atoms of 0.054 (2) Å for the O atoms. The but-oxy group adopts a fully extended all-trans conformation. In the crystal, mol-ecules are connected via C-Br⋯O halogen bonds [Br⋯O = ...
متن کامل1,5-Dibromo-2,4-dimethoxybenzene
In the title compound, C8H8Br2O2, all non-H atoms lie essentially in a common plane (r.m.s deviation of all fitted non-H atoms = 0.0330 Å). In the crystal, weak C-H⋯O hydrogen bonds connect the mol-ecules, forming chains which extend along the b-axis direction.
