A luminescent Eu(III) complex based on 2-(4', 4', 4'-trifluoro-1', 3'-dioxobutyl)-dibenzothiophene for light-emitting diodes.
Complex Eu(dbt)(3)(phen) (Hdbt=2-(4', 4', 4'-trifluoro-1', 3'-dioxobutyl)-dibenzothiophene, phen=1,10-phenanthroline) was synthesized. The complex emits red luminescence, characteristic of the (5)D(0)-->(7)F(J) (J=0-4) emission bands of Eu(3+) under near ultraviolet. A red conversion light-emitting diode (LED) device was fabricated by coating complex onto InGaN-based-LED chip that emits 395nm u...
متن کاملDesign and synthesis of some thiazolidin-4-ones based on (7-hydroxy-2-oxo-2H-chromen-4-yl) acetic acid.
(7-Hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid methyl ester(1) upon reaction with ethyl bromoacetate furnishes (7-ethoxycarbonylmethoxy-2-oxo-2H-chromen-4-yl)-acetic acid methylester (2), which on treatment with 100% hydrazine hydrate yields (7-hydrazinocarbonylmethoxy-2-oxo-2H-chromen-4-yl)-acetic acid hydrazide (3). The condensation of compound 3 with different aromatic aldehydes afforded a se...

متن کاملAntioxidant activity of some (7-hydroxy-2-oxo-2H-chromen-4-yl) acetic acid derivatives
A series of coumarin Schiff bases (7-(arylidenehydrazinocarbonylmethoxy)-2-oxo-2H-chromen-4-yl]acetic acid arylidenehydrazide) (4a-k) and N-(2-aryl-4-oxothiazolidin-3-yl)-2-{[4-(2-aryl-4-oxothiazolidin-3-yl)carbamoylmethyl]-2-oxo2H-chromen-7-yloxy}-acetamides (5a-k) were synthesized and evaluated for their antioxidant activity (scavenging of 1,1diphenyl-2-picryhydrazyl radical and phosphomolybd...
متن کامل7-Chloro-6,8-dinitroquinazolin-4(3H)-one acetic acid monosolvate
In the title compound, C(8)H(3)ClN(4)O(5)·C(2)H(4)O(2), both the nitro groups are close to perpendicular [dihedral angles = 67.62 (15) and 86.73 (12)°] to the almost planar quinazoline unit [r.m.s. deviation = 0.014Å]. In the crystal, both the quinazoline and acetic acid mol-ecules form inversion dimers linked by pairs of N-H⋯O and O-H⋯O hydrogen bonds, respectively. R(2) (2)(8) loops arise in ...
