We have developed a new synthetic protocol for the preparation of a microcrystalline powder (median size: X50 = 25 μm) of networked M6L4 cages 1a for the stationary phase of an affinity column on a greater than 50 g scale. Analogously to large singl

Infrared spectroscopy has been used to make the first experimental discrimination between molecules bound by physisorption on the exterior surface of carbon single-walled nanotubes (SWNTs) and molecules bound in the interior. In addition, the selecti

We investigate the effects of zero-point vibrational motion on the nuclear magnetic shielding constants of a large number of organic molecules. The vibrational corrections include anharmonic contributions from the potential energy surface and harmoni

A tripyrrole peptide-Hoechst conjugate (FPH-1) has been designed which recognizes nine dA/dT base pair A/T rich dsDNA sequences at subnanomolar concentrations and complexes its targets at near diffusion controlled rates to form a fluorescent product.

A spectroscopic study of the Fe(III)−EDTA−peroxide complex using electron paramagnetic resonance (EPR), low-temperature absorption (LT-ABS), variable-temperature−variable-field (VTVH) magnetic circular dichroism (MCD), and resonance Raman (rR)

A disulfide-bridged two-stranded α-helical coiled-coil peptide has been designed which undergoes a random coil to α-helical transition at pH 7 and 20 °C upon metal binding to two sites engineered into the molecule. The metal binding coiled-coil, d

The ultrafast dynamics in the interior of planar aligned multibilayers of 1,2-dilauroyl-sn-glycero-3-phosphocholine (dilauroylphosphatidylcholine, DLPC) are investigated using 2D IR vibrational echo spectroscopy. The nonpolar and water insoluble vibr

The first examples of crystallographically characterizable complexes of Tb(2+), Pr(2+), Gd(2+), and Lu(2+) have been isolated, which demonstrate that Ln(2+) ions are accessible in soluble molecules for all of the lanthanides except radioactive promet

A thorough ab initio study of how the addition of successive water molecules shifts the gas phase zwitterion-neutral equilibrium of the amino acid glycine toward that of the solution phase is presented. Of particular interest is the number of water m
