“…Schiff bases are formed as condensation products between an aldehyde and an amine to generate versatile ligands with large structural diversity. Complexation with metal ions can lead to a wide range of metal complexes used in catalysis as novel materials and as bioactive compounds. − These ligands offer several approaches to tailor a complex by changing the coordinating moieties of the Schiff base, substitution on the aromatic rings, and changes in the hydrophobicity of the ligands. , The non-innocent vanadium-Schiff base complexes represent a much smaller class of V-Schiff base complexes containing a redox active ligand. Early work by Pecoraro and others explored some of the chemistry of this class of complexes to map out structures and spectroscopic features of the parent and substituted systems. ,− However, as described previously, the Schiff base scaffold can form a vanadium(IV) complex but with catecholate co-ligands, the Schiff base ligand serves to stabilize the vanadium(V) oxidation state …”

A hydrophobic Schiff base catecholate vanadium complex was recently discovered to have anticancer properties superior to cisplatin and suited for intratumoral administration. This [VO(HSHED)(DTB)] complex, where HSHED is N-(salicylideneaminato)-N′-(2-hydroxyethyl)-1,2-ethanediamine and the non-innocent catecholato ligand is di-t-butylcatecholato (DTB), has higher stability compared to simpler catecholato complexes. Three new chloro-substituted Schiff base complexes of vanadium(V) with substituted catecholates as co-ligands were synthesized for comparison with their non-chlorinated Schiff base vanadium complexes, and their properties were characterized. Up to four geometric isomers for each complex were identified in organic solvents using 51 V and 1 H NMR spectroscopies. Spectroscopy was used to characterize the structure of the major isomer in solution and to demonstrate that the observed isomers are exchanged in solution. All three chloro-substituted Schiff base vanadium(V) complexes with substituted catecholates were also characterized by UV−vis spectroscopy, mass spectrometry, and electrochemistry. Upon testing in human glioblastoma multiforme (T98g) cells as an in vitro model of brain gliomas, the most sterically hindered, hydrophobic, and stable compound [t 1/2 (298 K) = 15 min in cell medium] was better than the two other complexes (IC 50 = 4.1 ± 0.5 μM DTB, 34 ± 7 μM 3-MeCat, and 19 ± 2 μM Cat). Furthermore, upon aging, the complexes formed less toxic decomposition products (IC 50 = 9 ± 1 μM DTB, 18 ± 3 μM 3-MeCat, and 8.1 ± 0.6 μM Cat). The vanadium complexes with the chloro-substituted Schiff base were more hydrophobic, more hydrolytically stable, more easily reduced compared to their corresponding parent counterparts, and the most sterically hindered complex of this series is only the second non-innocent vanadium Schiff base complex with a potent in vitro anticancer activity that is an order of magnitude more potent than cisplatin under the same conditions.

“…22 Many organic molecules with AIE features based on TAE have been developed for the application of fluorescent sensors, cell imaging, and organic lightemitting diodes. [23][24][25] Integration of an AIE unit and an acceptor group in one molecule with a multicolored switch and multistimuli-responsivity is rather difficult to achieve and has been rarely reported. 26,27 Therefore, it is very meaningful to design and exploit high contrast multi-stimulus-responsive emission materials based on TAE, which is of fundamental importance to understanding variable color-changing mechanisms and opens pathways to novel smart luminescent materials.…”

“…The probe 2-hydroxy-1-naphtaldehyde salicyloylhydrazone was described in detail. For the determination of yttrium in THF, a very sensitive fluorescent approach and the fluorescence method were developed based on the chelation reaction; they can detect traces of Y 3+ with a naked eye in sunlight [61]. The structures of the chemosensors 23-24 and their interactions with Y 3+ ion are shown in Figure 7.…”

The Schiff base was first synthesized by Hugo Schiff through the condensation reaction of primary amines with carbonyl compounds (aldehyde or ketone) in 1864. Schiff bases exhibit many structural and electrical characteristics that enable their use in a variety of fields, including medical and chemosensing. Schiff bases generate stable complexes when they bind with different metal ions. Schiff bases are employed as fluorescent turn-on/turn-off chemosensors for the detection of various metal cations, such as Hg2+, Cd2+, Cr3+, Pd2+, and As3+ in various materials due to their outstanding coordination ability. This chapter examines a variety of Schiff bases that are employed in chemosensing procedures for various metal ions (such as divalent and trivalent cations) in various biological, agricultural, and environmental settings.
