Journal ArticleDOI
Ultrafast time-resolved study of photophysical processes involved in the photodeprotection of p-hydroxyphenacyl caged phototrigger compounds.
Chensheng Ma,Wai Ming Kwok,Wing Sum Chan,Peng Zuo,Jovi Tze Wai Kan,and Patrick H. Toy,David Lee Phillips +6 more
TL;DR: The results provide important evidence for elucidation of the initial steps for the pHP deprotection mechanism and indicates that the triplet is the reactive precursor for pHP photorelease reactions for the compounds examined in this study.
Journal ArticleDOI
Ultrafast time-resolved transient absorption and resonance raman spectroscopy study of the photodeprotection and rearrangement reactions of p-hydroxyphenacyl caged phosphates.
Chensheng Ma,Wai Ming Kwok,Wing Sum Chan,Yong Du,Jovi Tze Wai Kan,Patrick H. Toy,David Lee Phillips +6 more
TL;DR: The solvent effect observed in conjunction with the leaving group dependence of the triplet decay dynamics are consistent with a concerted solvent assisted triplet cleavage through a heterolytic mechanism for the HPDP and HPPP photodeprotection process.
Journal ArticleDOI
Time-resolved resonance Raman study of the triplet states of p-hydroxyacetophenone and the p-hydroxyphenacyl diethyl phosphate phototrigger compound.
Chensheng Ma,Peng Zuo,Wai Ming Kwok,Wing Sum Chan,Jovi Tze Wai Kan,and Patrick H. Toy,David Lee Phillips +6 more
TL;DR: The temporal evolution at very early picosecond time scale indicates there is rapid intersystem crossing (ISC) conversion and subsequent relaxation of the excess energy of the initially produced energetic triplet state.
Journal ArticleDOI
Poly(ethylene glycol)-supported α,α,α-trifluoroacetophenone in dioxirane mediated alkene epoxidation reactions
Jovi Tze Wai Kan,Patrick H. Toy +1 more
TL;DR: The PEG-ketone reagent was found to be an effective homogeneous catalyst for the epoxidation of a variety of alkenes in the presence of Oxone® and was readily recovered from the reaction mixtures and reused.
Journal ArticleDOI
Sulfur- and selenium-based linkers in polymer-supported organic synthesis
Jovi Tze Wai Kan,Patrick H. Toy +1 more
TL;DR: The use of sulfur-and selenium-based linkers in polymer-supported organic synthesis (PSOS) is reviewed in this article, highlighting the work of the Nicolaou and Huang groups.
