Abstract
4,6-O-Ethylidene-N-(2-hydroxybenzylidene)-β-D-glucopyranosylamine (PL1) exhibits excited state intramolecular proton transfer (ESIPT) mechanism, which has been established by experimental and theoretical calculations. Further, PL1 selectively interacts with Lu3+ ion yielding a turn-on response in methanol, where the emission intensity of the former enhances (~15 fold) after metal ion interaction. The complexation has been investigated using various analytical tools like UV-visible absorption/emission, nuclear magnetic resonance spectroscopy and lifetime studies. The relative quantum yield of PL1 (0.0043) enhances to 0.1025 upon interaction with the Lu3+ ion. The studies on stoichiometry by Job's plot, ESI mass spectrometry and density functional theory calculations revealed the ligand-to-metal interaction in 2 : 1 ratio.
期刊介绍：
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
