Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 4341-76-8, Name is Ethyl 2-butynoate, SMILES is CC#CC(OCC)=O, belongs to esters-buliding-blocks compound. In a document, author is Koehne, Ingo, introduce the new discover, Recommanded Product: Ethyl 2-butynoate.
Functionalised phosphonate ester supported lanthanide (Ln = La, Nd, Dy, Er) complexes
A series of phosphonate ester supported lanthanide complexes bearing functionalities for subsequent immobilisation on semiconductor surfaces are prepared. Six phosphonate ester ligands (L1-L6) with varying aromatic residues are synthesised. Subsequent complexation with lanthanide chloride or -nitrate precursors (Ln = La, Nd, Dy, Er) affords the corresponding mono- or dimeric lanthanide model complexes [LnX(3)(L1-L3 or L5-L6)(3)](n) (X = NO3, Cl; n = 1 (Nd, Dy, Er), 2 (La, Nd)) or [LnCl(2)Br(L4-Br)(2)(L4-Cl)](n) (n = 1 (Nd, Dy, Er), 2 (La, Nd)) (1-32). All compounds are thoroughly characterised, and their luminescence properties are investigated in the visible and NIR spectral regions, where applicable.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4341-76-8 is helpful to your research. Recommanded Product: Ethyl 2-butynoate.
