Photofunctions in Hybrid Systems of Schiff Base Metal Complexes and Metal or Semiconductor (Nano)Materials

Abstract

Composite materials very often provide new catalytic, optical or other physicochemical properties not observed for each component separately. Photofunctions in hybrid systems are an interesting topic of great importance for industry. This review presents the recent advances, trends and possible applications of photofunctions of hybrid systems composed of Schiff base metal complexes and metal or semiconductor (nano)materials. We focus on photocatalysis, sensitization in solar cells (DSSC—dye sensitized solar cell), ligand-induced chirality and applications in environmental protection for Cr(VI) to Cr(III) reduction, in cosmetology as sunscreens, in real-time visualization of cellular processes, in bio-labeling, and in light activated prodrug applications.

Solubility of the Schiff Base Ligand and the Organoaluminum Supported by the Ligand in Pure Solvents: Characterization, Determination, Analysis, and Model Correlation

“…Schiff bases and organometallic compounds have flexible and versatile structures as well as high reactivity, allowing them to be used in a variety of fields such as catalysis, − pharmaceuticals, electrochemistry, sensors, etc. Among them, Schiff bases substituted by the F atoms have outstanding activity in the pharmaceutical field due to the increased interaction between drug molecules and receptors resulting from the electronegativity of the F atoms .…”

Crystal structure and Hirshfeld surface analysis of mono/bis(aqua-κO)[N-(2-oxidobenzylidene)valinato-κ3 O,N,O′]copper(II): dimeric Schiff base copper(II) complexes having different numbers of coordinated water molecules

“…They play an important and diverse role in coordination chemistry (Qiu et al, 2008;Li et al, 2010;Xue et al, 2009;Katsuumi et al, 2020). We recently published a review (Akitsu et al, 2022) of the synthesis of amino acid Schiff base-metal complexes. According to the literature, in general, Schiff bases and their metal complexes are multipurpose compounds and are extensively utilized in many research and industrial applications.…”

Recent Advances in Chiral Schiff Base Compounds in 2023

“…My (T.A. 's) recent review [23] that presents photofunctions of hybrid materials composed of Schiff base metal complexes and metal nanoparticles or semiconductors also dealt with ligand-induced chirality and applications. Here, again, the introduction of optical activity into Schiff bases at the molecular or material level (rather than at the crystalline level [24]) was occasionally observed.…”
