Osamu Yamane,Ken-ichi Sugiura,Hitoshi Miyasaka,Kazuya Nakamura,Tatsuhiko Fujimoto,Kazuki Nakamura,Takahiro Kaneda,Yoshiteru Sakata,Masahiro Yamashita +8 more
TL;DR: In this paper, pyrene-fused porphyrins via the oxidative intramolecular ring closure reactions of meso-pyrenylporphyrin were prepared.
Journal ArticleDOI
The first Janus [2]rotaxane
TL;DR: The first Janus [2]rotaxane 3 has been synthesized by bis-azo coupling of 2-naphthol-3,6-disulfonic acid with a Janus[2]pseudorotaxane 2 prepared by dimerization of 6-O-[(4-aminophenylazo)phenyl]-permethylated α-cyclodextrin and characterized by MALDI-TOF-MS and 1H NMR methods.
Journal ArticleDOI
Photoswitching of the association of a permethylated α-cyclodextrin-azobenzene dyad forming a Janus [2]pseudorotaxane☆
TL;DR: For achieving the on–off operation of the superstructure formation of hermaphrodite cyclodextrin derivatives, azobenzene-modified permethylated α-cyclodextrins, 1 and 2 were synthesized and formed Janus [2]pseudorotaxanes in CD3OD–D2O mixtures.
Journal ArticleDOI
New Large-Scale Preparations of Versatile 6-O-Monotosyl and 6-Monohydroxy Permethylated α-, β-, and γ-Cyclodextrins
Takahiro Kaneda,Tatsuhiko Fujimoto,Jun'ichiro Goto,Kaori Asano,Yoshitaka Yasufuku,Jone Hwa Jung,Chiaki Hosono,Yoshiteru Sakata +7 more
TL;DR: In this article, new practical methods for preparation of versatile 6-O-monotosyl and 6-monohydroxy permethylated α-, β-, and γ-cyclodextrins are described.
Journal ArticleDOI
Systematic Synthesis of Porphyrin Dimers Linked by Conjugated Oligoacetylene Bridges
Kazuya Nakamura,Tatsuhiko Fujimoto,Satoshi Takara,Ken-ichi Sugiura,Ken-ichi Sugiura,Hitoshi Miyasaka,Tomohiko Ishii,Masahiro Yamashita,Yoshiteru Sakata +8 more
TL;DR: In this article, a series of α,ω-bis(meso-porphyrinyl)oligoacetylenes were systematically prepared, and the exciton interaction between the porphyrins gradually decreased with increasing number of acetylenes.
