pKa Values of Guanine in Water: Density Functional Theory Calculations Combined with Poisson-Boltzmann Continuum-Solvation Model
Yun Hee Jang,William A. Goddard,Katherine T. Noyes,Lawrence C. Sowers,Sungu Hwang,Doo Soo Chung +5 more
TL;DR: In this article, the relative stabilities of tautomers of guanine in various environments and their pK_a values in aqueous solution were calculated using density functional theory (B3LYP) with the Poisson−Boltzmann continuum−solvation model.
Journal ArticleDOI

Seungjib Yum,Tae Kyu An,Xiaowei Wang,Wonho Lee,Mohammad Afsar Uddin,Yu Jin Kim,Thanh Luan Nguyen,Shuhao Xu,Sungu Hwang,Chan Eon Park,Han Young Woo +10 more
TL;DR: In this article, a series of benzotriazole-based semicrystalline π-conjugated polymers with noncovalent conformational locks for applications in polymer field effect transistors were reported.
Journal ArticleDOI

Mohammad Afsar Uddin,Mohammad Afsar Uddin,Tack Ho Lee,Shuhao Xu,Song Yi Park,Taehyo Kim,Seyeong Song,Thanh Luan Nguyen,Thanh Luan Nguyen,Seo-Jin Ko,Sungu Hwang,Jin Young Kim,Han Young Woo,Han Young Woo +13 more
TL;DR: In this paper, four different kinds of photovoltaic polymers were synthesized by controlling the intrachain noncovalent coulomb interactions through the incorporation of alkoxy- or alkylthio-substituted phenylene, 4,7-di(furan-2-yl)benzothiadiazole, and 4, 7-di (thiophen-2.yl) benzothiamide as a building block.
Journal ArticleDOI
Guest-induced reorganization of a self-assembled pd(ii) complex
TL;DR: In this article, a self-assembled two-dimensional Pd(II) complex derived from a bidentate ligand trans -1,2-bis(4-pyridyl)ethylene and (en)Pd(NO 3 ) 2 in D 2 O showed concentration dependent and guest-induced reorganization behavior.
Journal ArticleDOI
First Principles Calculations of the Tautomers and pKa Values of 8-Oxoguanine: Implications for Mutagenicity and Repair
Yun Hee Jang,Yun Hee Jang,William A. Goddard,Katherine T. Noyes,Lawrence C. Sowers,Lawrence C. Sowers,Sungu Hwang,Doo Soo Chung +7 more
TL;DR: First principles quantum mechanics are used in combination with Poisson-Boltzmann continuum-solvation model to investigate the relative stabilities and site-specific pK(a) values of various neutral and ionized tautomers of 8-oxoguanine.
