Web1,1′-Bisnaphthol (BINOL) has been successfully identified as a new organic photocatalyst framework for metal-free atom transfer radical polymerization (ATRP), and good control over the molecular weight, narrow dispersity and high chain-end fidelity is achieved under visible light mediation. The BINOL framewo WebThe high refractive index aromatic compound, binaphthol (BINOL), is readily incorporated into silicone polymer chains using the Piers-Rubinsztajn (PR) reaction; alternating and …

WebThe specific refractive index increment (dn/dc) of dilute polymer solutions, measured in light scattering experiments, is needed in the determination of the molecular weight, and the size and shape of polymers in solutions. The refractive index is defined as the velocity of light in vacuum relative to the velocity in the polymer. electric heating sheets

WebRefractive Index Database. The table below contains links to refractive index data for common materials. Each material in the database has refractive index listed as a function of wavelength over a range typically required for thin-film thickness measurement. WebThere is no single equation that accurately predicts the refractive index of a mixture. This reference discusses 9 approaches to estimating the refractive index of mixtures and provides the formula for each method. The simplest method is the Arago-Biot approach. It is reasonably reliable and is described by the following formula WebThe pK a values of fifteen BINOL type chiral phenolic catalysts were determined by the overlapping indicator method in DMSO via UV spectrophotometric titrations. The acidities cover the range from 9.30 to 16.43. The pK a gap between BINOL and 2-naphthol was explained by IR spectrum data, crystal structure and 1 H NMR.
