In the title compound, C(10)H(11)NO(2)S, the acetyl-acetone group crystallizes in the keto form with all the non-hydrogen atoms in the acetyl-acetone group approximately co-planar with a maximum atomic deviation 0.055 (2) Å; the dihedral angle between the acetyl-acetone group and the pyridine ring is 85.90 (6)°. An intra-molecular O-H⋯O hydrogen bond involving the acetyl-acetone group forms a six-membered ring.

The synthesis, Density Functional Theory (DFT) calculations, and photo physical characteristics of a range of quinoline derivatives have been described in the present work. Initially, the innovative derivatives are synthesized through the cyclization of 2-amino-5-nitrobenzophenone with either acetyl acetone or ethyl acetoacetate, followed by reducing the nitro group to an amine. Subsequently, these compounds undergo an acid-amine cross-coupling reaction.

Treatment of 3-formyl-acetyl-acetone with the amines benzyl-amine, -butyl-amine and ()-methyl-benzyl-amine led to the formation of the corresponding Schiff bases 3-[(benzyl-amino)-methyl-idene]pentane-2,4-dione, CHNO (), 3-[(-butyl-amino)-methyl-idene]pentan-2,4-dione, CHNO () and 3-{[()-benz-yl(meth-yl)amino]-methyl-idene}pentane-2,4-dione, CHNO (). The mol-ecules of all three compounds exist as enamine tautomers that contain a nearly planar amino-methyl-ene-pentane-2,4-dione core with a strong intra-molecular N-H⋯O hydrogen bridge. The group attached to the enamine N atom has no significant influence on the bond lengths and angles of the amino-methyl-ene-pentane-2,4-dione core.

Treatment of 3-formyl-acetyl-acetone with the isomeric -, - and -amino-benzoic acids led to the formation of the corresponding Schiff bases, namely, 3-[(2-carb-oxy-phenyl-amino)-methyl-idene]pentane-2,4-dione, , 3-[(3-carb-oxy-phenyl-amino)-methyl-idene]pentane-2,4-dione, , and 3-[(4-carb-oxy-phenyl-amino)-methyl-idene]pentane-2,4-dione, , all CHNO, that contain a planar amino-methyl-ene-pentane-2,4-dione core with a strong intra-molecular N-H⋯O hydrogen bridge. The carb-oxy-phenyl groups attached to the nitro-gen atom are almost coplanar to the central mol-ecular fragment. Depending on the position of the carboxyl unit, different supra-molecular structures with hydrogen-bonding networks are formed in the three title structures.

The anchoring group of a sensitizer may strongly affect the overall properties and stability of the resulting dye-sensitized solar cells (DSSCs) and dye-sensitized photoelectrosynthetic solar cells (DSPECs). The properties of seven perylene monoimide (PMI) dyes have been comprehensively studied for their immobilization on nanocrystalline NiO film. The PMI dyes differ only by the nature of the anchoring group, which are: carboxylic acid (PMI-CO H), phosphonic acid (PMI-PO H ), acetyl acetone (PMI-acac), pyridine (PMI-Py), aniline (PMI-NH ), hydroxyquinoline (PMI-HQ), and dipicolinic acid (PMI-DPA).

A new, selective and accurate spectrofluorimetric assay has been described for detection of Amisulpride and Memantine hydrochloride in pharmaceutical formulations and real plasma samples. The described assay depends on the reaction between the primary amino group of the selected drugs with acetyl acetone & formaldehyde in an acetate buffer of pH4.8.
