Synthesis, characterization and oscillator-vibrated near-infrared (NIR) luminescence of two pseudo-polymorphic [Yb4((OH)2-Salophen)4] complexes

Self-assembling of three rare structurally various homomultinuclear CuII complexes derived from a bis(salamo)-based multioxime ligand

“…Coordination chemistry is an important branch of chemistry and is involved many active research fields (Mirza et al, 2018;Liu et al, 2018aLiu et al, , 2019cYamamura et al, 2010;Wang et al, 2012;Duan et al, 2019;Zhang et al, 2020b;Cao et al, 2017). In salen-based ligands [R-CH N-(CH 2 ) n -N CH-R] and their corresponding homometallic and heterometallic complexes, due to their potential application values, intense research in modern coordination chemistry is still ongoing (Bhanja et al, 2020;Maity et al, 2020;Bag et al, 2020;Song et al, 2018;Majumdar et al, 2018;Zhang et al, 2015;Wang et al, 2009;Lo Presti et al, 2010). Therefore, the construction of novel and functional metal complexes has become a research hotspot of the salen-based ligands (Mü ller et al, 2017;Li et al, 2017Li et al, , 2018bFeng et al, 2012).…”

“…Therefore, the construction of novel and functional metal complexes has become a research hotspot of the salen-based ligands (Mü ller et al, 2017;Li et al, 2017Li et al, , 2018bFeng et al, 2012). With the further study of the salen-based ligand and its related N 2 O 2 -donor analogs and their complexes, they are widely used in the fields of catalytic reactions (Chakraborty et al, 2019;Abd El Sater et al, 2019;Mahapatra et al, 2017), nonlinear optical materials (Ke et al, 2018;Guo et al, 2020;Zhang et al, 2015), fluorescent materials and biochemistry (Tong et al, 2017;Pan et al, 2017;Bhunia et al, 2020;Jrad et al, 2019). Normally, the salenbased ligand and its related N 2 O 2 -donor derivatives are ISSN 2052-5206 prepared by gently heating the mixed solution of appropriate diamines and salicylaldehyde and its derivatives.…”
