Proton transfer plays a crucial role in physical, chemical, and biological macromolecular
systems, and the Excited-State Intramolecular Proton Transfer (ESIPT) effect is widely …

The development of specific and visually detectable fluorophores for the accurate and rapid
Pb 2+ recognization is crucial. In this study, we introduced a novel isophorone-derived …

In this study, a novel easy-to-prepare diethylaminophenol appended pyrimidine bis
hydrazone (HD) has been designed and developed. The probe exhibits excellent sequential …

In this paper, phenolphthalein and thiophene hydrazide are used as raw materials to design
and synthesize a fluorescent probe (FS) that can selectively detect trace amounts of Al 3+ …

Two Schiff base fluorescent-colorimetric probes, 4-(1-naphthalene-methylene amino)
benzoic acid (L a) and 3-hydroxyl-4-(1-naphthalene-methylene amino) benzoic acid (L b) …

A naphthylidene-diimine L 2 was newly designed, and its structure was identified by
elemental analysis and spectroscopic methods. The effect of temperature, acid–base and …

The constant release of heavy metal ions into the environment has posed a serious threat to
the environment as well as organisms. It became necessary to monitor their limits in water …

New mononuclear metal complexes (M= Mn (II), Fe (III), Co (II), Ni (II), Cu (II) and Zn (II))
derived from a novel tetradentate N2O2 Schiff base ligand (H2L) were efficiently produced …

A coumarin-based chemosensor FCOC (1 N'-(furan-2-carbonyl)-2-oxo-2H-chromene-3-
carbohydrazide) was synthesized, and its sensing behaviors towards different analytes were …

A new acylhydrazone fluorescent sensor (VN62) with excited intramolecular proton transfer
(ESIPT) characteristics has been designed and synthesized through condensation of o …
