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

Abstract

The design and synthesis of electrically conductive coordination polymers (CPs) are of special interest due to their applications in the fabrication of many environmentally benign emerging technologies such as molecular...

Heterometallic MIL-125(Ti–Al) frameworks for electrochemical determination of ascorbic acid, dopamine and uric acid

“…As a new emerging class of highly ordered porous materials, metal-organic frameworks (MOFs), also known as porous coordination polymers (PCPs), are constructed from metal-containing nodes and organic linkers. [1][2][3][4][5] The structures and structure-related properties of MOFs can be tuned by judicious design of both constituents at the molecular level. 6 Owing to their unlimited structural diversity and functional tunability, 7,8 MOFs have become one of the most fascinating classes of materials in numerous areas including gas storage and separation, [9][10][11] ion exchange, 12 chemical sensing, [13][14][15] catalysis, [16][17][18] energy harvesting, 19,20 and biomedicine.…”

Comparison of Electrical Conductivity and Schottky Behavior of 4‐[2‐(9‐anthryl)vinyl]pyridine Based Two 1D Coordination Polymers of Zn(II) and Cd(II)

“…In this regard, a significant effort has been dedicated by the scientists to judiciously fabricate CPs that exhibit semiconducting behavior. [31][32] From literature survey, it has been observed that CPs based on d 10 metal ions (Zn/Cd) are capable of exhibiting conductivity and can be used as electronic devices. Thus, a substantive number of CPs based on Zn/Cd metals has been synthesized and thoroughly investigated by our group and others.…”

“…Till date, a large number of CPs have been made using phenyl or napththalene based N-donor ligands that undergo π•••π interactions, generating congenial environment for charge transport. [31][32] However, utilization of anthracene based CPs for electrical conductivity is relatively less explored. In this regard, highly conjugated polycyclic aromatic hydrocarbon (PAH) based ligand, 4-[2-(9-anthryl)vinyl]pyridine (4-avp) [37] could be a good choice for better π•••π stacking and large extent of charge transportation through space.…”

“…Consequently, the most important aspect is to modify the electrical coupling between the organic ligands and metal centers in order to promote delocalization and increase conductivity. In this regard, a significant effort has been dedicated by the scientists to judiciously fabricate CPs that exhibit semiconducting behavior [31–32] . From literature survey, it has been observed that CPs based on d 10 metal ions (Zn/Cd) are capable of exhibiting conductivity and can be used as electronic devices.…”

“…In case of charge transport “through space”, supramolecular interactions, such as π⋅⋅⋅π stacking contacts play major role. Till date, a large number of CPs have been made using phenyl or napththalene based N ‐donor ligands that undergo π⋅⋅⋅π interactions, generating congenial environment for charge transport [31–32] . However, utilization of anthracene based CPs for electrical conductivity is relatively less explored.…”
