چکیده
The title compound, C(16)H(11)N(3)O(2), displays a trans configuration with respect to the azo group. The mol-ecule is non-planar; the maleimide ring forms a dihedral angle of 42.35 (4)° with the benzene ring bonded to its N atom and the mean plane of this benzene ring is rotated by 21.46 (8)° with respect to the azo group mean plane, which, in turn, forms a dihedral angle of 24.48 (7)° with the 'terminal' benzene ring. Mol-ecules in the crystal are π-π stacked along the [100] direction with a mean inter-planar distance of 3.857 (1) Å. In addition, C-H⋯O inter-actions link them into double layers parallel to the ac plane.

The title compound, C(31)H(25)NO(6), has a structure related to other 3,4-diaryl-substituted maleic anhydride derivatives which have been shown to be useful as photochromic materials. The dihedral angles between the maleimide ring system and the benzene rings bonded to it are 44.48 (3) and 17.89 (3)°, while the angles between each of the latter rings and the corresponding ether bridging connect...

withdrawing groups and an electron-donating group. The electron-withdrawing groups are further conjugated with a double bond in the ring. The light-absorption characteristics of the molecule are expected to be modified by changing the substituents attached to the molecule. This indicates that the molecule can be one of the basic components in designing functional dyes. It is therefore of partic...

component for functional dyes because it contains two electronwithdrawing and one electron-donating groups. Studies to understand how substituents to the 1H-pyrrole-2,5-dione skeleton influence its structure and properties are of particular interest from the viewpoint of the development of novel functional dyes. We determined the structure of 1,3,4triphenyl-pyrrole-2,5-dione (Fig. 1(I))1 and de...
