Heteroleptic [Bis(oxazoline)](dipyrrinato)zinc(II) Complexes: Bright and Circularly Polarized Luminescence from an Originally Achiral Dipyrrinato Ligand
Julius F. Kögel,Shinpei Kusaka,Ryota Sakamoto,Ryota Sakamoto,Toshiki Iwashima,Mizuho Tsuchiya,Ryojun Toyoda,Ryota Matsuoka,Takamasa Tsukamoto,Junpei Yuasa,Junpei Yuasa,Yasutaka Kitagawa,Tsuyoshi Kawai,Hiroshi Nishihara +13 more
TL;DR: Heteroleptic zinc(II) complexes synthesized using achiral dipyrrinato and chiral bis(oxazoline) ligands show bright fluorescence with quantum efficiencies of up to 0.70, and the luminescence is circularly polarized despite the achirality of the dipyrinato ligand.
Journal ArticleDOI
Dual emission caused by ring inversion isomerization of a 4-methyl-2-pyridyl-pyrimidine copper(I) complex.
Michihiro Nishikawa,Kuniharu Nomoto,Shoko Kume,Keiichi Inoue,Makoto Sakai,Masaaki Fujii,Hiroshi Nishihara +6 more
TL;DR: A new convertible copper(I) complex using 2-pyridyl-4-methylpyrimidine and diphosphine as ligands exhibited mechanical bistability based on the inversion motion of the pyrimidine ring, leading to dual luminescence behavior.
Journal ArticleDOI
Redox-Assisted Ring Closing Reaction of the Photogenerated Cyclophanediene Form of Bis(ferrocenyl)dimethyldihydropyrene with Interferrocene Electronic Communication Switching
TL;DR: Reversible switching of electronic communication between the ferrocene (Fc) moieties by photoisomerization of the DHP moiety is exhibited and a novel ring closing reaction induced by oxidation of the Fc moieties is demonstrated.
Journal ArticleDOI
GPR68, a proton-sensing GPCR, mediates interaction of cancer-associated fibroblasts and cancer cells.
Shu Z. Wiley,Krishna Sriram,Wenjing Liang,Wenjing Liang,Sarah E. Chang,Randall French,Thalia McCann,Jason K. Sicklick,Hiroshi Nishihara,Andrew M. Lowy,Paul A. Insel +10 more
TL;DR: CAF‐expressed GPR68 is a mediator of low‐pH‐promoted regulation of the tumor microenvironments, in particular to PDAC cell‐CAF interaction and may be a novel therapeutic target for pancreatic and perhaps other types of cancers.
Journal ArticleDOI
Synthesis of Azo-Conjugated Metalladithiolenes and Their Photo- and Proton-Responsive Isomerization Reactions
TL;DR: It is indicated that the protonation is a common feature for the azo-conjugated metalladithiolenes, but trans-to-cis photoisomerization is strongly dependent on the electronic structure of the trans form or a steric effect in the cis form.
