One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, HPLC of Formula: C4HBr2NO2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1122-10-7, Name is 3,4-Dibromo-1H-pyrrole-2,5-dione, molecular formula is C4HBr2NO2
Large Changes in Fluorescent Color and Intensity of Symmetrically Substituted Arylmaleimides Caused by Subtle Structure Modifications
Herein we report on four diarylmaleimides based on 3- or 2-substituted benzothiophene (M3S or M2S) and benzofuran (M3O or M2O), which show very different emission properties: aggregation-caused quenching (ACQ), aggregation-induced emission (AIE), and dual-state strong emission (DSE) in both solution and solid states. Their emission color in the solid state can be adjusted from green?yellow into red. M2O displays strong red solid-state emission at 630 nm with a quantum yield of 46.3 %. Single-crystal X-ray diffraction analysis confirms that their large distinction in solid-state emission originates from their different packing structures: hydrogen-bonded organic frameworks (HOFs) for M3S, a staggered structure for M3O, J-aggregation for M2S, and weak H-aggregation for M2O. HOF of M3S and weak H-aggregation of M2O make them produce inverse-type piezochromic fluorescence: blueshifted ?turn-on? and redshifted ?turn-off? emission, respectively. These results provide new insight in fluorescence manipulated by subtle structure modification.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, HPLC of Formula: C4HBr2NO2, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 1122-10-7
