Journal ArticleDOI
Anisotropic Charge Distribution and Anisotropic van der Waals Radius Leading to Intriguing Anisotropic Noncovalent Interactions
TL;DR: This work elucidate the unusual features and origin of the anisotropic noncovalent interactions in the ground and excited states of the 2nd and 3rd row elements belonging to groups IV–VII and provides an understanding of their unusual molecular configuration, binding and recognition modes involved in new types of molecular assembling and engineering.
Journal ArticleDOI
Solvent rearrangement for an excited electron of the iodide-water pentamer
Han Myoung Lee,Kwang S. Kim +1 more
TL;DR: In this paper, the solvent rearrangement process for the excited electron in the iodide-water pentamer was investigated using density functional and ab initio calculations, and the transformation pathway was elucidated.
Journal ArticleDOI
Linear and nonlinear optical properties of indeno[2,1-b]fluorene and its structural isomers
Simil Thomas,Kwang S. Kim +1 more
TL;DR: The optical gaps calculated by the DMRG method, employing the long-range interacting Pariser-Parr-Pople model, show good agreement with the experimental values as compared to those calculated by DFT, MP2, and CASPT2 methods.
Journal ArticleDOI
Noncovalent Functionalization with Alkali Metal to Separate Semiconducting from Metallic Carbon Nanotubes: A Theoretical Study
Nannan Li,Geunsik Lee,Jae Won Yang,Hyun-Chul Kim,Min Sun Yeom,Ralph H. Scheicher,Jai Sam Kim,Kwang S. Kim +7 more
TL;DR: In this article, the van der Waals interactions between semiconducting and metallic single-walled carbon nanotubes (SWNTs) were investigated and it was shown that a K atom binds the SWNTs more strongly than a K+ ion.
Journal ArticleDOI
A "turn-on" fluorescent probe for the detection of permanganate in aqueous media.
Genggongwo Shi,Mushtaq Ahmed Shahid,Muhammad Yousuf,Farzana Mahmood,Lubna Rasheed,Lubna Rasheed,Christopher W. Bielawski,Kwang S. Kim +7 more
TL;DR: A novel carbazole-based probe was synthesized and found to exhibit fluorescence upon introduction to potassium permanganate in aqueous media and the underlying mechanism is proposed to proceed through a series of tandem proton and electron transfer processes.
