Abstract

With the increase in demand of electronic devices in the modern civilization, research in material science is being projected to grow in faster rate. In this facet, coordination polymer (CP) based electronic device is one of the promising candidates to the material researchers. Herein, two new Zn(II) and Cd(II) based one-dimensional (1D) CPs, denoted as Zn(4-avp)2(5-nip) â� (solvent)x (1) and Cd(4-avp)(5-nip)(CH3OH) (2) have been synthesized using relatively less explored highly conjugated polycyclic aromatic hydrocarbon (PAH) based monodentate ligand, 4-2-(9-anthryl)vinylpyridine (4-avp) and bidentate linker 5-nitroisophthalic acid (H25-nip). In this instance, the CP 1 creates 1D chain polymer, while CP 2 is made up with 1D ladder polymer. It is interesting to note that both the CPs exhibit semiconducting nature and generate metal-semiconductor (MS) junction Schottky barrier diodes (SBDs). However, Cd-based CP 2 shows higher charge transport as compared to Zn-CP 1, which could be due to stronger Ï�â� â� â� Ï� contacts as well as larger size of Cd metal in CP 2. The experimental results are well corroborated with theoretical density of states (DOS) calculations. © 2024 Wiley-VCH GmbH.
