Strategy for the improvement of electrical conductivity of a 3D Zn(ii)-coordination polymer doubly bridged by mesaconato and pyridyl-isonicotinoyl hydrazide based Schottky diode device

Abstract

Out of many stimulating research fields, the search for energy materials is taking of highest priority in recent times due to issues related to sustainable development. Explicit investigation in energy...

Two Water-Stable Zn(II) Coordination Polymers as Luminescent Sensors for Detection of Uric Acid in Serum, MnO4–, and Cr(VI) Oxo-Anions in Tap Water

“…Two CPs exhibit similar absorption peaks at 303 and 295 nm as the ligands, which can be attributed to the π → π* transitions of the ligands in their structures. The corresponding band gaps of 1 and 2 were calculated to be 3.30 and 3.51 eV, respectively, according to the E g calculation formula ( Ahv ) 1/2 = B ( hv – E g ) …”

“…The corresponding band gaps of 1 and 2 were calculated to be 3.30 and 3.51 eV, respectively, according to the E g calculation formula (Ahv) 1/2 = B(hv − E g ). 37 Powder X-ray Diffraction and Thermogravimetric Analyses. Powder X-ray diffraction (PXRD) was measured as shown in Figure S3, and the peaks of the synthesized samples for both CPs match well with the simulated ones, indicating that the synthesized samples have good phase purity.…”

Coordination polymers: a promising candidate for photo-responsive electronic device application

“…The conductivity has been increased in the presence of light at room temperature (DC conductivity: dark, 2.98 × 10 −4 S m −1 and light, 7.01 × 10 −4 S m −1 ), which indicates the photo-responsive behavior of the material. 74…”

Mn(II) 3D Coordination Framework with Mixed 5-Aminoisophthalato and Pyridyl-isonicotinoyl Hydrazone Bridges: Structure, Electrical Conductivity, Anticancer Activity, and Drug Delivery

“…Normally, carboxylate-bridging ligands would not conduct electricity due to the presence of insulating C-centers while the presence of metal (even diamagnetic) knots controls the energy difference between valence and conduction bands and make them helpful for electrical communicators and/or semiconductors. − In the past few years, it has been explored that CPs are working as better electrical conductors and storage systems than conventional electrical devices. Some excellent porous conducting polymers (PCPs) of Zn­(II), Cd­(II), and few other transition metal ions are reported recently. − To the best of our knowledge, Mn­(II)-based CPs are still rare in the literature for serving as electrical conductors. It is assumed that d 5 high-spin electronic configuration of Mn­(II) having the highest magnetic field may accelerate the electronic properties of the materials.…”
