Journal ArticleDOI
Excitation Energy Transport Processes of Porphyrin Monomer, Dimer, Cyclic Trimer, and Hexamer Probed by Ultrafast Fluorescence Anisotropy Decay
Hyun Sun Cho,Hanju Rhee,Jae Kyu Song,Chang Ki Min,Masayoshi Takase,Naoki Aratani,Sung Cho,Atsuhiro Osuka,Taiha Joo,Dongho Kim +9 more
TL;DR: These cyclic porphyrin array systems have proven to be useful in understanding energy migration processes in a relatively weak interaction regime in light of the similarity in overall structures and constituent chromophores to natural light-harvesting arrays.
Journal ArticleDOI
Self-Duplex Formation of an APy-Substituted Oligodeoxyadenylate and Its Unique Fluorescence
TL;DR: Unexpected homoadenine self-duplexes are formed when pyrene units are bound covalently to the deoxyadenosine bases at specific distances (1,4 relationships).
Journal ArticleDOI
Noncollinear phase matching in fluorescence upconversion.
Hanju Rhee,Taiha Joo +1 more
TL;DR: This work investigates noncollinear sum-frequency generation in a time-resolved fluorescence upconversion experiment to eliminate group-velocity mismatch (GVM), a major mechanism that deteriorates time resolution.
Journal ArticleDOI
Ultrafast transient dynamics of Zn(II) porphyrins: Observation of vibrational coherence by controlling chirp of femtosecond pulses
TL;DR: In this paper, the authors obtained detailed information on the excited state dynamics and subsequent structural changes based on the comparison between the frequency spectra retrieved from the oscillatory features in the transient absorption and fluorescence temporal profiles and the ground stat...
Journal ArticleDOI
Effect of conformational heterogeneity on excitation energy transfer efficiency in directly meso-meso linked Zn(II) porphyrin arrays
Tae Kyu Ahn,Zin Seok Yoon,In Wook Hwang,Jong Kuk Lim,Hanju Rhee,Taiha Joo,Eunji Sim,Seong Keun Kim,Naoki Aratani,Atsuhiro Osuka,Dongho Kim +10 more
TL;DR: It is revealed that the solvation dynamics as well as the conformational dynamics contributes significantly to the energy relaxation processes of linear porphyrin arrays, which no longer serve as good energy transmission elements in donor-acceptor linked systems.
