The kinetics of dissociation of (18-crown-6, Na/sup +/)/sup 1/ in propylene carbonate (PC), acetonitrile (AN), pyridine (PY), and acetone (AC) have been determined by /sup 23/Na NMR. Two mechanisms of exchange, namely unimolecular dissociative and bi

In this work, a novel NMR method for the identification of preferential coordination sites between physiologically relevant counterions and nucleic acid bases is demonstrated. In this approach, the NMR cross-correlated relaxation rates between the ar

A droplet of an ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate, bmim.BF(4)) is immersed in an immiscible liquid (n-hexadecane) and electrowetted on a flat Teflon AF1600-coated ITO electrode. The static contact angle decreases significant

The solvent dependence of the excited state dynamics of [Ru(bpy)(2)(dppp2)](2+) (bpy = 2,2'-bipyridine, dppp2 = pyrido[2',3':5,6]pyrazino[2,3-f][1,10]phenanthroline) were investigated using ultrafast transient absorption spectroscopy. In contrast to

We report a rationale for identifying superior dyes for stimulated-emission depletion (STED) microscopy. We compared the dyes pPDI and pTDI, which displayed excellent photostability in single-molecule spectroscopy. Surprisingly, their photostability

A microporous metal-organic framework, PCN-14, based on an anthracene derivative, 5,5‘-(9,10-anthracenediyl)di-isophthalate (H4adip), was synthesized under solvothermal reaction conditions. X-ray single crystal analysis revealed that PCN-14 consist

Variations in the hydrogen bond network of the Oxy-1.5 DNA guanine quadruplex have been monitored by trans-H-bond scalar couplings, (h2)J(N2N7), for Na(+)-, K(+)-, and NH(4)(+)-bound forms over a temperature range from 5 to 55 degrees C. The variatio
