New imidazolium systems bearing two pyrene groups as fluorescent chemosensors for anions and anion induced logic gates
Ha Na Lee,N. Jiten Singh,Sook Kyung Kim,Ji Young Kwon,Yoo Young Kim,Kwang S. Kim,Juyoung Yoon +6 more
TL;DR: In this article, two new imidazolium systems bearing two pyrene groups have been synthesized and the binding properties of these hosts were examined via fluorescent changes, and the fluorescent changes of host 2 upon the addition of anions were also utilized as a NOR logic gate and an INH logic gate.
Journal ArticleDOI
Structures, energetics, and spectra of aqua-cesium (I) complexes: an ab initio and experimental study.
Maciej Kołaski,Han Myoung Lee,Young Cheol Choi,Kwang S. Kim,Pilarisetty Tarakeshwar,Dorothy J. Miller,James M. Lisy +6 more
TL;DR: The vibrational frequency shifts were investigated as a function of the number of water molecules and the frequency characteristics with and without the presence of outer-shell water molecules to identify specific hydrogen-bonding structures present in the experimental spectra.
Journal ArticleDOI
Fluorobenzene and p-difluorobenzene microsolvated by methanol: An infrared spectroscopic and ab initio theoretical investigation
K. Buchhold,B. Reimann,S. Djafari,Hans-Dieter Barth,Bernhard Brutschy,Pilarisetty Tarakeshwar,Kwang S. Kim +6 more
TL;DR: In this article, the infrared ion depletion spectra were taken in the region of the OH and CH stretches of methanol, where the methenol molecules form subclusters, which are weakly hydrogen bonded to either the aromatic π-system (πOH) or to the fluorine substituent (σF) and a CH group (σCH).
Journal ArticleDOI
Water-cluster distribution with respect to pressure and temperature in the gas phase
TL;DR: The small-water-cluster distribution in the gas phase is studied to aid the better analysis of certain cluster properties in an experiment and the mole fractions of the water clusters along the vapor pressure of the condensed phase are investigated.
Journal ArticleDOI
Structure, vertical electron-detachment energy, and O–H stretching frequencies of e+(H2O)12
TL;DR: In this article, the first comprehensive ab initio study on an excess electron bound to the water dodecamer is performed to find out if this wet electron can be regarded as a precursor of the fully solvated electron.
