4-Nitrophenyl methacrylate

4-Nitro­phenyl methacrylate

The title compound, C(10)H(9)NO(4), was obtained serendipitously during the preparation of benzyl cyclo-hexyl-carbamate. The mol-ecule consists of two approximately planar parts, the nitro-phenyl ring and the rest of the non-H atoms, with a dihedral angle of 55.05 (6)° between the two segments. The crystal structure is stabilized by weak C-H⋯O inter-actions and π stacking [3.753 (1) Å] along th...

(4-Chlorobenzoyl)(4-chlorophenyl)amino 3-(2-nitrophenyl)propanoate

In the title hydroxamic acid derivate, C22H16Cl2N2O5, the nitro-substituted benzene ring forms dihedral angles of 14.11 (15) and 16.08 (15)°, with the 4-chloro-benzoyl and 4-chloro-phenyl benzene rings, respectively. The dihedral angle between the chloro-substituted benzene rings is 2.28 (13)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains along [100].

Intramolecular electron transfer reactions in meso-(4-nitrophenyl)-substituted subporphyrins.

A2B-type meso-(4-nitrophenyl)-substituted subporphyrins have been synthesized and shown to undergo very fast photoinduced intramolecular charge separation (CS) and charge recombination (CR) between the subporphyrin core and the meso-4-nitrophenyl group in CH2Cl2 as probed by femtosecond time-resolved transient absorption spectroscopy. Red-shifted emissions were detected from charge-separated st...

Crystal structure of 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole.

A nonlinear optical chromophore, 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole, was investigated by X-ray crystallography. The study focused on coplanarity among several aromatic rings, including phenyls and imidazole. Two phenyl rings with NMe2 groups are twisted by 46.39(3) degrees from each other. However, they are twisted by 23.05(5) degrees and 46.84(3) degrees from the imidazo...
