New Fluorimetric Alkali and Alkaline Earth Metal Cation Sensors Based on Noncyclic Crown Ethers by Means of Intramolecular Excimer Formation of Pyrene
Yoshio Suzuki,Tatsuya Morozumi,Hiroshi Nakamura,Masatsugu Shimomura,Takashi Hayashita,Richard A. Bartsh +5 more
TL;DR: In this article, 2,2,3, and 5 pyrenes at both terminals of polyoxyethylene compounds were synthesized, and their complexation behavior with alkaline earth cations was investigated by fluorescence spectrometry, fluorescence lifetimes, and 1H NMR spectrometric.
Journal ArticleDOI
New Fluorescent “Off−On” Behavior of 9-Anthryl Aromatic Amides through Controlling the Twisted Intramolecular Charge Transfer Relaxation Process by Complexation with Metal Ions
TL;DR: New fluorophores based on linear polyether N,N‘-[oxybis(3-oxapentamethylenoxy)-2-phenyl]bis(9-anthracenecarbonamide) (3) and its analogues (2 and 4) have been synthesized, and their complexation pr...
Journal ArticleDOI
Discriminating detection between Mg2+ and Ca2+ by fluorescent signal from anthracene aromatic amide moiety.
TL;DR: Novel fluorescent reagents 1 and 2 were synthesized and in the absence of metal ions, the fluorescence emissions were quite weak, but their intensities were much greater in the presence of alkaline earth metal ions.
Journal ArticleDOI
Novel Mg2+-responsive fluorescent chemosensor based on benzo-15-crown-5 possessing 1-naphthaleneacetamide moiety
TL;DR: In this article, a new fluorescent ionophore for Mg2+, 4′-(1-naphthaleneacetamido)benzo-15-crown-5 (1), was synthesized, and its complexation behavior in acetonitrile was investigated by means of UV and fluorescence spectrometry.
Journal ArticleDOI
Photoisomerization of azobenzocrown ethers. Effect of complexation of alkaline earth metal ions
TL;DR: In this paper, the effects of complexed metal ions on trans−cis photoisomerization reactions of two azobenzene compounds having a crown ether ring, 1a (small ring) and 1b (large ring) were investigated.
