Photoinduced organometallic mediating radical polymerization of acrylates mediated by CoII complexes of non-symmetrical tetradentate Schiff-base ligands

Review of quantitative and qualitative methods for monitoring photopolymerization reactions

“…RT-FTIR spectroscopy, according to numerous literature sources, has been and remains a useful technique for studying the kinetics of photopolymerization reactions according to radical, cationic, and hybrid mechanisms, in addition to various exposure conditions, types of light source used, coating thickness, monomer and oligomer reactivity or efficiency of newly developed photoinitiating systems. 79–85…”

“…[71][72][73][74][75][76][77][78] RT-FTIR spectroscopy, according to numerous literature sources, has been and remains a useful technique for studying the kinetics of photopolymerization reactions according to radical, cationic, and hybrid mechanisms, in addition to various exposure conditions, types of light source used, coating thickness, monomer and oligomer reactivity or efficiency of newly developed photoinitiating systems. [79][80][81][82][83][84][85] For free-radical photopolymerization, RT-FTIR measurement consists of repeated scanning of the sample at short intervals and observing in real-time changes in the IR absorption spectrum, for example, changes in both the intensity and position characteristic of (meta)acrylic groups, i.e. : [86][87][88][89] • a band at 810-816 cm −1 characteristic of a twisting vibration of the -CHvCH 2 group,…”

Photo‐induced organo‐manganese‐mediated radical polymerization of acrylates under LED irradiation

“…30 Our research group has also investigated Co (II) and Ni (II) complexes bearing symmetrical and nonsymmetrically substituted N 2 O 2 tetradentate Schiff base ligands in the photo-OMRP of acrylates and vinyl acetate under LED irradiation at 390 nm and in the range of 400-800 nm. 23,31,32 Koumura et al reported that a dinuclear manganese carbonyl complex [Mn 2 (CO) 10 ] exhibits high effectiveness in achieving rapid and controlled radical polymerization of vinyl acetate under visible light in the presence of an alkyl iodide initiator. 33 However, to the best of our knowledge, there are no reports on photo-OMRP mediated by manganese complexes.…”

Structural characterisation of novel mononuclear Schiff base metal complexes, DFT calculations, molecular docking studies, free radical scavenging, DNA binding evaluation and cytotoxic activity

“…As a result, novel complexes that interact with DNA are currently of tremendous concern in terms of design and manufacture. [23] Based on the previous considerations, the current research reported the synthesis of novel Co(II), Cu(II), Fe(III), Mn(II), Ni(II) and Zn(II) complexes generated from a symmetrical tetradentate N 2 O 2 Schiff base ligand produced via a simple thermal condensation reaction between 4,5-dimethyl-1,2-phenylendiammine and 2-hydroxy-1-naphthaldehyde. Elemental microanalysis, conductometric assays, magnetic susceptibility and numerous spectroscopic examinations were used to adequately describe the newly synthesised materials.…”
