Polyoxometalate functionalized matrix material: synthesis, characterization, reductive and thermal degradation kinetics

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

Microwave assisted synthesis of a mono organoimido functionalized Anderson polyoxometalate.

The synthesis of an aliphatic organoimido functionalized polyoxometalate has been achieved through a microwave assisted reaction protocol in the absence of any activating reagents. Characterization of the pendant amine containing polyanion [Mo6O18NC(OCH2)3MnMo6O18(OCH2)3CNH2](5-) (1) includes single crystal XRD, NMR, ESI-MS, IR and SAXS.

One-pot Synthesis and Characterization of Highly Functionalized Thiazoles

A facile and efficient one-pot three-step process for the synthesis of 5-acetyl-2-imino-4-methylthiazoles via the cyclocondensation of 3-thiocyanatoacetylacetone with various hydrazine or hydrazide derivatives in EtOH has been developed. 3-Thiocyanatoacetylacetone itself has been synthesized as the intermediate from substitution reaction of thiocyanate with 3-chloroacetylacetone. B...

Reductive Degradation of Chlorinated Organics by Membrane-Supported Nanoparticles: Synthesis, Characterization and Modeling Study

Synthesis and Characterization of Fluorescent Polyoxometalate Nano-/Microrods

Fluorescent nano-/microrods of the polyoxometalate (POM) K4H[Eu(α-SiW11O39)(H2O)2] · 17H2O were obtained in aqueous solution by a conventional synthesis method. The nano-/microrods have been characterized by elemental analysis and FT-IR, UV/Vis, and TG-DTA data, and their morphology was examined by ESEM-FEG, showing that the average ratio of diameter to length is 1 : 20. The obtained nano-/micr...
