A prominent bathochromic shift effect of indole-containing diarylethene derivatives.
The potential implication of photochromic materials with absorption and reactivity in the near-infrared region is far-reaching. In this work, three novel bisindole-containing diarylethene derivatives 1o–3o have been successfully synthesized and their photochromic behaviour exhibits a strong bathochromic shift effect compared with bisbenzothiophene diarylethene 4o. These new bisindole-diarylethe...
متن کامل(E)-N′-(2-Hydroxybenzylidene)furan-2-carbohydrazide
In the title compound, C(12)H(10)N(2)O(3), the dihedral angle between the benzene ring and the furan ring is 16.12 (13)°. The conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds with the keto group as acceptor lead to strands along [001]. The mol-ecule displays a trans configuration with respect to the C=N and N-N bonds.
متن کاملN′-(Butan-2-ylidene)furan-2-carbohydrazide
The title Schiff base compound, C(9)H(12)N(2)O(2), was obtained from a condensation reaction of butan-2-one and furan-2-carbohydrazide. The furan ring and the hydrazide fragment are roughly planar, the largest deviation from the mean plane being 0.069 (2)Å, but the butanyl-idene group is twisted slightly with respect to this plane by a dihedral angle of 5.2 (3)°. In the crystal, inter-molecular...
متن کامل(E)-N′-(2-Fluorobenzylidene)furan-2-carbohydrazide
The title compound, C(12)H(9)FN(2)O(2), was prepared by the reaction of 2-fluoro-benzaldehyde and furan-2-carbohydrazide. The furan ring is disordered over two sets of sites with refined occupancies of 0.60 (3):0.40 (3). The major and minor components of the furan ring make dihedral angles of 51.9 (6) and 38.0 (10)°, respectively, with the benzene ring. In the crystal, mol-ecules are linked via...
متن کاملN′-(4-Chlorobenzylidene)furan-2-carbohydrazide monohydrate
In the title compound, C(12)H(9)ClN(2)O(2)·H(2)O, the dihedral angle between the aromatic rings is 13.9 (2)° and an intra-molecular N-H⋯O hydrogen bond occurs. In the crystal structure, the components are linked by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds.
