(JOHN WILEY & SONS, 2008-08)Novel ruthenium (II) complexes were prepared containing 2-phenyl-1,8-naphthyridine derivatives. The coordination modes of these ligands were modified by addition of coordinating solvents such as water into the ethanolic ...
-
(Taylor & Francis Ltd., 1997)The syntheses and structural properties of four liquid crystalline monomers are presented. They are prepared by two different reaction pathways. Transition temperatures and phase characterization were done by DSC, ...
-
(TAYLOR & FRANCIS LTD, 1993)We present the synthesis and a description of the physical properties of several organic dyes containing stilbene as well as azomethine groups. The preparations of all compounds started from a common precursor, ...

Synthesis and characterization of polynuclear complexes of molybdenum carbonyl derivatives with ... (Elsevier Ltd, 1998)Novel mono- and didentate ferrocenylphosphines containing complexes, [Mo2(CO)6(dfpp)2(μ-pa)] (dfpp = diferrocenylphenylphosphine) and [Mo2(CO)6(μ-dppf)(μ-pa)], have been isolated and characterized by infrared and electronic ...
-
(Elsevier, 2013)A series of novel complexes of the Ru(L)2(CO)2 L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (complex 1), and type Ru(acac)2(L)(CO) with L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (complex 2), 2-(2′- bromophenyl)-1,8-naphthyridine ...
-
(Taylor & Francis, 2015)The syntheses of two new series of ruthenium(II) complexes incorporating substituted 4-phenylterpyridine, triphenylphosphine, and chloride (A Series) or hydride (B Series) are reported. In both series 4-phenyl-terpyridine ...
-
(Elsevier B.V., 2019)An electrochemical sensor for the determination of Cu(II) in bivalve mollusks using a glassy carbon electrode modified with p-tert-butylcalix [4]arene-bis-cyrhetrenylimine (Cy2(Calix [4])) by square wave anodic stripping ...
-
(Sociedad Chilena de Química, 2008-06)In this work we describe the synthesis and characterization of the Co2Cu4Te4O11Cl4 phase prepared by the hydrothermal technique. From the polycrystalline X-ray diffraction pattern the obtained new phase was indexed in the ...
-
(Wiley, 2017)A series of novel 3-indolylpropyl derivatives was synthesized and evaluated for their binding affinities at the serotonin-1A receptor subtype (5-HT1AR) and the 5-HT transporter (SERT). Compounds 11b and 14b exhibited the ...
-
(2013)A series of novel hydroxy-coumarin-chalcone hybrid compounds 2a-i has been synthesized by employing a simple and efficient methodology. An electrochemical characterization using cyclic voltammetry and ESR spectroscopy were ...

-
(Royal Society of Chemistry, 2020)A new series of heteroaryl nitrones were synthesized and evaluated as free radical traps due to the results showed in our previous report. The physicochemical characterization of these new nitrones by electron spin resonance ...
-
(Freund Publishing House Ltd, 2000)A straightforward synthesis of a group of 4-alkylamino-6-nitroquinolines starting from a common intermediate, 5,8-dimethoxy-6-nitro-4(1H)quinolone 3, is described. These compounds were tested in vitro as potential ...
-
(2012)Gold nanoparticles (AuNPs) have been extensively used in biological applications because of their biocompatibility, size, and ease of characterization, as well as an extensive knowledge of their surface chemistry. These ...
-
(AMER CHEMICAL SOC, 1996-04)A new series of liquid-crystalline Schiff base lanthanide compounds of the general formula (L''H)(2)L''MX(2) was prepared (L''H = H2n+1CnOC6H3(OH)CHNCmH2m+1; n = 7, 12; m = 14, 18; M = La, Tb, Dy, Er, Nd, Ho, Eu, Pr, and ...
-
(Royal Soc Chemistry, 2017)The simple reaction of chitosan with metallic salts yields (chitosan) (MLn)(x), MLn = MnCl2, CoCl2, NiCl2, macromolecular complexes which, after a thermal treatment at 800 degrees C under air, give nanostructured Mn2O3, ...
-
(Royal Society of Chemistry, 1998)The UV irradiation of [Re(η5-C5Me5)(CO)3] in the presence of C6F6 effected intermolecular C-F and intramolecular C-H activation generating [Re(η6-C5Me4CH2)(CO) 2(C6F5)] 1a in two isomeric forms. In the major isomer the CH2 ...
