The vibrational spectra of 4-(dimethylamino)benzaldehyde (DABA) and its zinc complex are presented and vibrational assignments are proposed. Significant differences between the spectra of the parent molecule and the complex are observed. Examination of the form of the normal modes facilitates explanation of proposed frequency shifts of ring modes upon complexation. The spectra of the complex are interpreted by employing a quinonoid-type structure for the DABA ligand. 相似文献

Two novel luminescent boron compounds, BPh2(2-(2-quinolyl)naphtho[b]imidazolato) (1) and BPh2(2-(2-quinolyl)benzimidazolato) (2), have been synthesized by the reactions of triphenylboron with appropriate ligands, 2-(2-quinolyl)naphtho[b]imidazole (QNI) and 2-(2-quinolyl)benzimidazole (QBI), respectively. The structure of 1 was determined by single crystal X-ray diffraction, while 2 by spectroscopic methods. The structure of 1 reveals that the boron center is four coordinated. Several types of OLED possessing different colors were fabricated by using 1 as emitter. For the three-layer OLED with the structure ITO/NPB/2/Alq3/Mg-Ag, an emission band covering the whole visible region from 400 to 750 nm with the maximum brightness of 320 cd/m2 was observed, indicating a perfect white light OLED (CIE = 0.33, 0.37). Compounds 1 and 2 form a new family of organometallic emitting materials which could be of interest for practical application. 相似文献

Inner complex compounds (ICCs) and molecular adducts based on 2-(2-pyridyl)indandione-1,3 have been synthesized for the first time. The structure of the ligand (the preferred tautomer) and the complexes has been studied using X-ray crystallography, 1H NMR spectroscopy, and IR spectroscopy. 相似文献

A procedure has been developed for the synthesis of substituted 2-methylquinolin-4-ylthiuronium salts by reaction of 2-methyl-4-chloroquinoline with N-substituted thioureas. Alkaline hydrolysis of these salts yields 2-methyl-4-quinolyl isothiocyanate instead of the expected 2-methylquinoline-4-thiol. 相似文献

3-[(1-Oxo-1H-isoindol-3-yl)(phenyl)methylidene]-2,3-dihydro-1H-isoindol-1-one, 3-[(1-oxo-1H-isoindol-3-yl)(1-naphthyl)methylidene]-2,3-dihydro-1H-isoindol-1-one, and 3-[(1-oxo-1H-isoindol-3-yl)(9-anthryl)methylidene]-2,3-dihydro-1H-isoindol-1-one were prepared by the reactions of phthalimide with phenylacetic, 1-naphthylacetic, and 9-anthrylacetic acids, respectively. Heating of these precursors with stearic acid in the presence of zinc oxide yielded zinc complexes of meso-trans-diphenyldihexadecyltetrabenzoporphyrin, meso-trans-di(1-naphthyl)dihexadecyltetrabenzoporphyrin, and meso-trans-di(9-anthryl)dihexadecyltetrabenzoporphyrin, respectively. Treatment of the metal complexes with HCl yielded the porphyrin bases. The spectral properties of the compounds were studied. 相似文献

A reaction of phthalimide with phenylacetic acid in the presence of zinc oxide furnished 3-oxoisoindolenyl-3'-oxoisoindolinylidene-1,1'-benzylidine which at heating with 1-naphthylacetic acid in the presence of zinc oxide provided zinc meso-trans-diphenyldi(1-naphthyl)tetrabenzoporphin complex. Proceeding from this compound a meso-trans-diphenyldi(1-naphthyl)tetrabenzoporphin was prepared. The spectral characteristics of compounds obtained were studied. 相似文献

A ligand 1,3-bis(1-benzylbenzimidazol-2-yl)-2-oxopropane (Bobb) and the zinc(II) complex, [Zn(Bobb)2](picrate)2 · 2DMF, were synthesized and characterized by elemental analyses, electrical conductivities, IR, and UV. The crystal structures of the ligand and the zinc complex have been determined by single crystal X-ray diffraction. The ligand displays a V-shaped configuration and the Zn(II) cation is six-coordinate by four nitrogens and two oxygens from Bobb. The N4O2 donor set is a distorted octahedron. 相似文献

Abstract A biocompatible zinc (II) complex based on a tetradentate N,N,O,O-type salen ligand was synthesized, characterized and used for the solvent-free ring-opening polymerization (ROP) of L-lactide in bulk at 180?°C to prepare high molecular weight poly(L-lactide) (Mn : 82,600?Da; Mw : 140,000?Da; PDI: 1.70). Poly(L-lactide) (PLLA) was characterized using FTIR, 1H NMR, 13C NMR, GPC, TGA, DSC, WAXD, and MALDI-ToF. Kinetic measurement was carried out and first-order behavior to monomer was observed. The k app was found as 6?±?0.001?×?10?4?s?1. The biocompatibility of the PLLA was confirmed by in vitro cytotoxicity against NIH/3T3 fibroblast cell line and can be used in biomedical applications. 相似文献

The electronic structures and reactivity indexes (RI) of 2-(4-R-2-quinolyl)thiophenes and 5-(4-R-2-quinolyl)-2,2-dithienyls (R = H, COOH, COOC2H5, and NHCOCH3) and their protonated forms were calculated by the Pariser-Parr-Pople (PPP) method. The peculiarities of the geometrical and -electron structures were established. The calculated reactivity indexes are compared with experimental data on the electrophilic substitution reactions of the investigated compounds. A qualitative agreement between the calculated values and the experimental data was established. It is shown that quinoline derivatives of thiophene are less reactive than the corresponding dithienyl compounds in electrophilic substitution reactions.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 751–754, June, 1979. 相似文献
