A rigid hydrogen‐bonded organic framework (HOF) was constructed from a C3‐symmetric
hexatopic carboxylic acid with a hydrophilic 18‐crown‐6‐ether (18C6) component. Despite …

The use of methoxypoly (ethylene glycol)(mPEG) in PEG conjugates of proteins and non-
protein therapeutic agents has led to the recognition that the polymer components of such …

Although core–shell copper metal nanoclusters are important emerging materials for
practical applications and fundamental scientific research, their synthesis lags behind that of …

The geometry of a molecule plays a significant role in determining its physical and chemical
properties. Despite its importance, there are relatively few studies on ring puckering and …

Several standard semiempirical methods as well as the MMFF94 force field approximation
have been tested in reproducing 8 DLPNO‐CCSD (T)/cc‐pVTZ level conformational …

Macrocyclic molecule 1 that has two saloph coordination sites was designed and
synthesized. The macrocycle 1 was easily converted into the corresponding metallohosts 2 …

Complexes of 18-crown-6 ether (18C6) with four protonated amino acids (AAs) are
examined using infrared multiple photon dissociation (IRMPD) action spectroscopy utilizing …

A series of phenylenediamines containing the NO2 group and 3 to 0 fluorine atoms and 18-
crown-6 ether were used to study the dependence of the stoichiometry and supramolecular …

Argon-tagged alkali metal ion-crown ether complexes were generated in the gas phase and
investigated using a combination of infrared predissociation (IRPD) spectroscopy, density …

The vibrational, Raman, and IR, spectra of the five 12-crown-4 (12c4) complexes with Li+,
Na+, K+, Rb+, and Cs+ alkali metal cations were measured. Except for a small shift of the …
