Electrochemical properties of a series of differently substituted vanadyl salen complexes were investigated using cyclic voltammetry in different solvents. Results obtained show that the salen structure stabilizes the oxidized forms and that the effects of substituents on the oxidation potential correlate with the electronic density of the metal. Also the role of the donicity of the solvent in influencing the redox potentials of the studied complexes has been evidenced. Moreover, the variations of the observed potentials can be qualitatively correlated to the catalytic activity of vanadyl salen derivatives in the oxidation of thioethers.

A series of novel, simple, and colorful Salen ligands (56 samples), salicylaldehyde-based bis-Schiff bases, linking with different non-conjugated alkyl bridges ((CH2)n, n = 2-9, 12; cyclohexyl) and containing different electron-accepting (-NO2, -F, and -Cl), electron-donating (-OMe, -OH, and -NEt2), or sterically hindering (-t-butyl) substituents or a π-extended system (naphthalene ring) have been designed and synthesized. The photophysical properties of these Salen ligands can be well-tuned by the introduction of side functional substituents, π-extended systems, and central N-alkyl chain bridges. It is unusual that they contain a small π-conjugated system but display strong blue, green, and red aggregation-induced emission (AIE) with large Stokes shifts (up to 162 nm) and high fluorescence quantum yields (up to 0.44 and 0.75 in water and in solid, respectively). Combining with their advantages of AIE and good stability and biocompatibility, the Salen ligands can be potentially used in mechanofluorochromism (crystal-defect-induced emission) and living cell imaging. Moreover, the inherent relationships between their chemical structures and AIE properties are studied, which provide unequivocal insights for the design of AIE-active dyes.
Major impact of N-methylation on cytotoxicity and hydrolysis of salan Ti(IV) complexes: Sterics and electronics are intertwined

A series of Ti(IV) complexes containing diamino bis(phenolato) "salan" type ligands with NH coordination were prepared, and their hydrolysis and cytotoxicity were analyzed and compared to the N-methylated analogues. Substituting methyl groups on the coord
