Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 97-99-4, Name is (Tetrahydrofuran-2-yl)methanol, molecular formula is , belongs to Tetrahydrofurans compound. In a document, author is Powers-Riggs, Natalia E., SDS of cas: 97-99-4.
Solvent independent symmetry-breaking charge separation in terrylenediimide guanine-quadruplex nanoparticles
G-quadruplex assemblies are a promising tool for self-assembling pi -stacked chromophore arrays to better understand their photophysics. We have shown that coupling a single guanine moiety to terrylenediimide (TDI) produces a structure (GTDI) that self-assembles in tetrahydrofuran (THF) into a nearly monodisperse guanine-quadruplex structure having 16 pi -stacked layers (GTDI(4))(16). The TDI surfaces were determined to have a high degree of cofacial overlap and underwent quantitative symmetry-breaking charge separation (SB-CS) upon photoexcitation. Here, we more deeply examine the relationship between solvent and aggregate formation and develop insights into structure-function relationships over a variety of solvent polarities and hydrogen-bonding capabilities. At high concentrations, GTDI assembles into guanine-quadruplex structures (GTDI(4))(16) in THF and toluene, as well as (GTDI(4))(9) in pyridine and benzonitrile. Transient absorption spectroscopy shows that SB-CS occurs in all solvents, regardless of their static dielectric constants, but the SB-CS yield is determined by structure. Solvent polarity independent SB-CS generation is also observed in GTDI films, where there is a complete absence of solvent.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 97-99-4, in my other articles. SDS of cas: 97-99-4.
