A Theoretical Study of the Stability and Dielectric Constants of Molybdate-Phosphonic Acid Complex
In this work, we investigated the stability of Molybdate-Phosphonic Acid (MPA) complex by density functionaltheory (DFT) computations in six solvents with the dielectric constant ranging from 1.92 to 10.36. The methodsare used for calculations are B3LYP and B3PW9 I that have been studied in two series of basis sets: D95nand6-31+G (d,p) for hydrogen and oxygen atoms; LANL2DZ for Mo and Phosphoru...

15 صفحه اولAnhydrous proton conductivities of squaric acid derivatives.
In this communication, we introduce squaric acid derivatives as anhydrous proton conductors. We report the synthesis, characterization and proton conductivities of four squaric acid derivatives. The anhydrous proton conductivity of one of the derivatives was 2.3 × 10(-3) S cm(-1) at 110 °C, comparable to the conductivity of molten 1H-1,2,3-triazole or 1H-imidazole.

متن کاملSquaric Acid Diethylester: A Simple and Convenient Coupling Reagent
A new method for the covalent modification of poly mers in a two-step process is described. Squaric acid di ethylester reacts with primary or secondary aliphatic amines selectively to ester amides. It is shown for the first time that this class of compounds react with poly meric systems containing amine functionalities (e.g. g-amino groups of proteins) in aqueous solution, form ing stable s...
