The most widely used NMR method to measure diffusion is suboptimal for inorganic ions. A robust and superior alternative is available when strong field gradients (>1000 G/cm) can be used.
1H/19F diffusion NMR and 19F GEST NMR are utilized to characterize the encapsulation of bulky isosteric guests into the hexameric capsules of resorcin[4]arene and pyrogallol[4]arene.
Therapeutic deep eutectic solvents (THEDSs) are the best exemplification of green alternative formulations of active pharmaceutical ingredients (APIs) that offer superlative properties of APIs.
Attaching three Lewis acid functions to the TBTQ scaffold gave tridentate acids. Their ability to complex (poly-)Lewis bases and aggregate sizes were studied by solution NMR including DOSY NMR.
Utilizing lanthanide-modified cyclodextrins and implementing the 19F-paraGEST method, up to three different co-existing populations of Ln-β-CD-guest complexes were experimentally identified, despite having similar thermodynamic and kinetic properties.
