Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， category: catalyst-ligand, Which mentioned a new discovery about 4411-80-7
The invention relates to macrocyclic rare earth complexes which consist of at least one rare earth salt complexed by a macrocyclic compound of formula (I): STR1 in which: the bivalent radicals A, B, C and D, which are identical or different, are hydrocarbon chains optionally containing one or more heteroatoms, at least one of said radicals containing at least one molecular unit or essentially consisting of a molecular unit possessing a triplet energy greater than the energy of the emission level of the complexed rare earth ion, at least one of said radicals consisting of a substituted or unsubstituted nitrogen-containing heterocyclic system in which at least one of the nitrogen atoms carries an oxy group, and it being possible for one of the radicals C or D not to exist; and X1 and X2, which are identical or different, are hydrogen or a hydrocarbon chain (CH2)n optionally interrupted by 1 or more heteroatoms, n being an integer from 1 to 10, with the proviso that if the radicals A and/or B are a nitrogen-containing heterocyclic system in which at least one of the nitrogen atoms carries an oxy group, the radicals C and/or D are selected from biquinolines, biisoquinolines, bipyridines, terpyridines, coumarins, bipyrazines, bipyrimidines and pyridines, and to their use for reducing the perturbations in a fluorescent assay.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, category: catalyst-ligand, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 4411-80-7
