New Advances in Chemical Research, May 2021. The prevalence of solvent effects has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. In an article, author is Ristic, Predrag, once mentioned the application of 1591-31-7, Name is 4-Iodo-1,1′-biphenyl, molecular formula is C12H9I, molecular weight is 280.1, MDL number is MFCD00019028, category is thiomorpholine. Now introduce a scientific discovery about this category, Electric Literature of 1591-31-7.
Four silver-based coordination polymers, {[Ag(L)(2)](BF4)}(infinity) (1), {[Ag(H2BTC)(L)]center dot(H3BTC)}(infinity) (2), {[Ag-2(H2BTEC)(L)(2)]..3.33H(2)O}(infinity) (3), and [Ag(H(25)SSA)(L)](infinity) (4), were synthesized using thiomorpholine-4-carbonitrile (L) as the primary ligand and three aromatic polyoxoacids as coligands: trimesic (H3BTC), pyromellitic (H4BTEC), and 5-sulfosalicylic acid (H(35)SSA). Compounds 1 and 3 are two-dimensional, while 2 and 4 are one-dimensional. L acts as a bis-monodentate ligand, while the Ag(I) ion is three-coordinated in 2 and four-coordinated in all of the other compounds. The tetrahedral coordination of Ag(I) in 3 leads to an almost complete absence of intermolecular interactions with the metal center. All compounds show reasonable photocatalytic activity for photocatalytic degradation of mordant blue 9 dye, with reaction rates in the 0.036-0.056 min(-1) range. Changes in the reaction rates can be correlated with the type and coordination of the coligand. Complex 3 exhibits photoluminescence at 77 K, while 4 exhibits photoluminescence at both room temperature and 77 K. Luminescence lifetimes indicate electronic transitions of singlet parentage, where transitions are allowed. A TD-DFT study determined the contributions of individual singlet-singlet electronic excitations to the fluorescence, indicating that metal- intraligand transitions are responsible for luminescence in both complexes.
