“…Hydro(solvo) thermal methods are widely applied in synthesis of new CPs, since their products have high purity, good dispersion, are easily controlled, etc. 120,[145][146][147][148] The hydro(solvo)thermal reactions are associated with using organic or inorganic solvent at high temperature (usually 80-260 C) and autogeneous pressure in a closed system (as a rule, teon-lined autoclaves or glass vessels). 14 An obvious advantage of hydro(solvo) thermal methods is that they make it possible to alleviate the solubility problems of chelating ligands and improve the reactivity of the reagents during crystallization.…”

“…After intercalating the base pairs of DNA, the π* orbital of the intercalated ligand could couple with the π orbital of base pairs, thus decreasing the π – π * transition energy which marks in the bathochromism. On the other hand, the coupling of π orbital was partially filled by electrons, thus decreasing the transition probabilities and concomitantly, resulting in the hypochromism …”

An unique Schiff base ligand, formed by the condensation reaction of 2aminobenzothiazole with curcumin and its Cu(II), Ni(II), Co(II) and Zn(II) complexes incorporating 2,2′-bipyridine as coligand were synthesised. They were characterized via analytical and spectroscopic methods. The complexes adopt square planar geometry. Their antimicrobial activity and photocatalytic efficiency on Congo red dye molecule were explored. It is found that all the complexes are antimicrobial active and show higher activity than the ligand. The nuclease activity of the above metal complexes was also assessed by absorption titration, fluorescence, viscosity and gel electrophoresis assay. The complexes bind CT DNA through intercalation mode. The data reveal that the above synthesised metal(II) complexes are found to be effective metallonucleases. The gel electrophoresis results exhibit that the metal complexes cleave pBR322 plasmid DNA in presence of hydrogen peroxide effectively compared to the ligand. The synthesised metallonucleases should lead to a new era for the logical sketch of dominant agents for probing and targeting nucleic acids. This exploration reveals that Cu(II) complex has a valued biological and photochemical profile.

“…Different secondary interactions assemble the motifs to form a large surface area to collect photons in illumination conditions, which causes transfer of excited electrons from highest occupied molecular orbital (HOMO) to lowest unoccupied molecular orbital (LUMO). , The photoconductivity over the polymeric molecule–electrode interface occurs via excitation of charge carriers and migration over the lattice followed by charge separation. In this aspect, we are able to design two Pb(II)-based coordination polymers − and are useful to fabricate optoelectronic devices.…”

[Pb2(bdc)1.5(aiz)]n (1) and [Pb2(bdc)1.5(aiz)(MeOH)2]n (2) (H2bdc = 1,4-benzene dicarboxylic acid, aiz = (E)-N′-(thiophen-2-ylmethylene)isonicotinohydrazide) have been synthesized, and structural characterization has been established by X-ray analysis and thermogravimetric analysis (TGA). Here, bdc2– links two Pb(II) centers and the aiz ligand binds the metal centers in two different manners: chelating and monodonating. Thus, polymerizations have taken place from the combination of mixed ligand system. Optical band gaps have been studied via UV measurements. Again, the experimental and calculated (from density functional theory (DFT)) band gaps agree well and the semiconducting properties of synthesized polymeric materials have been approved. Thus, optoelectronic and photonic devices can be made by this type of coordination polymers (CPs). The I–V representative curves of 1 (device-A) and 2 (device-B) in both dark and illuminated conditions show that device-A has a higher magnitude of current than device-B. Dark- and photo-conductivity values of device-A are calculated as 2.94 × 10–6 and 6.12 × 10–6 S m–1, respectively, whereas for device-B, the values of dark- and photo-conductivity are 2.92 × 10–7 and 3.66 × 10–7 S m–1, respectively, at room temperature.
