Abstract:

1,3,5-triaryl-2-pyrazolines are organic luminophores with arylic radicals that show a wide biological activity and are used as liquid scintillators and electro-optic materials. Experimental. Eleven 2-pyrazolines were synthesized from phenylhidrazine and chalcones of the 8-hydroxyquinoline series: 3-(8-hydroxyquinolin-5-yl)-1-(3-R)-phenylprop-2-enone and 1-(8-hydroxyquinolin-5-yl)-3--(3-R)-phenylprop-2-enone, where R = H, CH3, OCH3, N(CH3)2, Cl, Br, and NO2.

8-Hydroxyquinoline and derivatives exhibit multifunctional properties, including antioxidant, antineurodegenerative, anticancer, anti-inflammatory and antidiabetic activities. In biological systems, elevation of intracellular calcium can cause calpain activation, leading to cell death.

Abstract:

8-hydroxyquinoline (oxine) is a widely known and frequently used chelating agent, and the pharmacological effects of the core molecule and its derivatives have been studied since the 19th century. There are several synthetic methods to modify this core. The Mannich reaction is one of the most easily implementable examples, which requires mild reaction conditions and simple chemical reagents. The three components of the Mannich reaction are a primary or secondary amine, an aldehyde and a compound having a hydrogen with pronounced activity.

Tris(8-hydroxyquinoline) aluminum crystals were grown under controlled P<sub>8-Hq</sub> [0.1–11.3 Torr] and their cell parameters were measured.

Abstract:

Two new 8-hydroxyquinoline (8-HQ) derivatives, namely 5-((4-chlorobenzene) diazene) -8-hydroxyquinoline (N-HQ) and 5-((4-chlorobenzene) methylene amino) -8-hydroxyquinoline (C-HQ), were designed and synthesized. Their structures were characterized by 1H NMR, 13C NMR, FT-IR and HR-MS. Their physical and photoelectrochemical properties were studied by absorption, emission, electrochemistry and thermog ravimetry. In addition, the gaussian program was used to calculate the geometric configurations of the two derivatives. Since N-HQ has an approximate planar configuration, it is packed in a highly

Abstract:

The treatment of anodic porous alumina (APA) plates in heated water containing 8-hydroxyquinoline (HQ) produces crystalline tris(8-hydroxyquinoline)aluminum (Alq3) microbelts about 5–10 μm wide and 5–20 μm long. These microbelts were found to aggregate to form flower-like structures on the surface. X-ray diffraction studies indicated that the Alq3 microbelts are composed of an α-phase having a meridional structure. The Alq3 microbelts exhibited green photoluminescence with a peak at around 520 nm. Scanning electron microscope images and energy dispersive X-ray spectra showed that this reaction

Abstract:

An efficient, easy and one pot synthesis for the Friedel-Craft acetylation reaction of quinolines was developed. The reaction between 8-hydroxyquinoline and acetyl/benzoyl chloride in nitrobenzene immediately flocculates as yellow precipitate. On further addition of Lewis acid causes the Friedel-Craft acetylation leads to formation of acetylated quionlines in good yields. The structure of compound 5-acetyl-8-hydroxyquinoline (3) was confirmed by single crystal X-ray diffraction studies. The compound crystallizes in the monoclinic crystal system with the space group P21/c. The synthesized acety
