Abstract:
The ortho-phenylene compounds ortho-[(XH)(YH)C6H4] (XH, YH = NH2, SH, OH) react with Co(BF4)2•6H2O and Tripod (CH3C(CH2PPh2)3) to give the five-coordinate Co(III) complexes [Tripod-Cobalt-(ortho-(X)(Y)C6H4)]+ (X, Y = NH, O, S), 1-6.The structures of 1—6 have been characterized by X-ray analyses of appropriate salts. The compounds have further been characterized by IR, NMR, UV-VIS and cyclovoltammetric measurements.As a compound analogous to 1—6, but containing the saturated chelate ligand [(S)C2H4(S)]2- instead of the conjugated ortho-phenylene type ligands of 1-6, [Tripod-Cobalt-((S)C2H4(S))]

Abstract:
Liquid crystals (LCs) are compounds that have properties between isotropic liquids and solid crystal materials. Although there is not a parameter to predict this behavior, the liquid crystals reported until now have common characteristics, for example rigid groups such as columns or rods within its structures, and long hydrocarbon chains that give flexibility. In this work we report the synthesis and characterization of LCN,N'-(1,4-phenylene bis (methanylylidene)) bis (4-(hexyloxy) aniline). The compound was characterized by infrared (IR), raman and1H-nuclear magnetic resonance (1H-NMR) spectr

Trinuclear Schiff base complexes were synthesized by using p-phenylene diamine, 2,3-pentanedione and 3-aminocoumarin and Cu (II), Ni (II), Mn (II), Zn(II) and Cr(III) chloride salts. The category of compound was [M3LCl6]. All trinuclear compounds were analyzed by C, H&N analysis and spectral studies. Mechanism of thermal analysis of trinuclear Schiff base metal complexes was studied. The electrophoresis data confirmed that Schiff base compounds cleaved DNA with Hydrogen peroxide.

Abstract:
Synthesis, X-ray diffraction, and Fourier transform infrared spectroscopy of aliphatic–aromatic aramid oligomers are reported with the aim of shedding light on the effect of end-chain substituent on the morphology and structure of poly(para-phenylene terephthalamide) or PPTA. Three types of X-ray powder diffraction patterns were observed: one similar to that of PPTA form I, one similar to that of PPTA form II, and an additional form never reported. Some compounds, differing by their internal distribution of amide–aromatic rings, adopt two different crystal structures, whereas compounds having

Abstract:
The dispiro title compound (systematic name: 1,4,6,13-tetraoxa-2,3-benzodispiro[4.1.4.2]tridecane), C13H14O4, is an asymmetric orthocarbonic acid ester of an aromatic and an aliphatic vicinal diol. C—O bond lengths at the orthoester centre show a typical difference of about 0.06 Å, as has been observed for related spiro esters with an aliphatic component that does not impose steric strain in the vicinity of the orthocarbonic acid centre. The C—O bond-length differences are also observed in density functional theory (DFT) calculations, thus ruling out a decisive influence of intermolecular forc

Natural bromophenols are important secondary metabolites in marine algae. Derivatives of these bromophenol are potential candidates for the drug development due to their biological activities, such as antioxidant, anticancer, anti-diabetic and anti-inflammatory activity. In our present study, we have designed and synthesized a series of new methylated and acetylated bromophenol derivatives from easily available materials using simple operation procedures and evaluated their antioxidant and anticancer activities on the cellular level.

Various model radicals were synthesized and studied for their spin coupling by ESR spectroscopy. Diphenoxyl radical 7 is an indirect spin coupling model with long range conjugation. Diphenoxyl radical 12 is a direct coupling model with shorter conjugation. The ESR spectra of the both diradicals were studied to understand their spin interactions. In order to understand spin delocalization further in these radical systems, two other model compounds with simpler structure, 14 and 15, were designed and synthesized, and their ESR spectra studied.

Abstract:
Conjugated polymers are materials that have attracted much attention from the research community because of their charge and energy transport properties. In this sense, it is necessary to understand the mechanism behind exciton transfer in this particular class of systems. However, direct application of procedures done for different organic compounds is not straightforward for long polymeric chains, because such procedures would be computationally impracticable. In that matter, alternative treatments are required. In this work, we perform spectrum simulations for poly-thiophene (PTH) and poly(
