A questionable excited-state double-proton transfer mechanism for 3-hydroxyisoquinoline
Jinfeng Zhao,Jinfeng Zhao,Junsheng Chen,Yanling Cui,Jing Wang,Lixin Xia,Yumei Dai,Peng Song,Fengcai Ma +8 more
TL;DR: Two excited state proton transfer mechanisms of 3-hydroxyisoquinoline in cyclohexane and acetic acid (ACID) were investigated based on the time-dependent density functional theory (TDDFT), suggesting a different double-proton transfer mechanism from the one proposed previously.
Journal ArticleDOI
Competitive excited-state single or double proton transfer mechanisms for bis-2,5-(2-benzoxazolyl)-hydroquinone and its derivatives
TL;DR: Based on the new ESIPT mechanism, the observed fluorescence quenching can be satisfactorily explained and the potential barrier heights among the local minima on the S1 surface imply competitive single and double proton transfer branches in the mechanism.
Journal ArticleDOI
New excited state proton transfer mechanisms for 1,8-dihydroxydibenzo[a,h]phenazine
TL;DR: The calculated results show that the intramolecular hydrogen bonds were formed in the S0 state, and upon excitation, the intra-chemical hydrogen bonds between -OH group and pyridine-type nitrogen atom would be strengthened in theS1 state, which can facilitate the proton transfer process effectively.
Journal ArticleDOI
Theoretical Insights Into the Excited State Double Proton Transfer Mechanism of Deep Red Pigment Alkannin.
TL;DR: A novel mechanism that polar aprotic solvents can contribute to the first-step proton transfer (PT) process in the S1 state, and nonpolar Solvents play important roles in lowering the potential energy barrier of the second-step PT reaction.
Journal ArticleDOI
Exploring and elaborating the novel excited state dynamical behavior of a bisflavonol system
TL;DR: In this article, the dual hydrogen-bonded 1,4-bis-(3-hydroxy-4-oxo-4H-chromen-2-yl)-benzene (bisflavonol) system was investigated in detail.
