A novel supramolecular Zn(ii)-metallogel: an efficient microelectronic semiconducting device application

Abstract

A unique strategy for the synthesis of a supramolecular metallogel employing zinc ions and adipic acid in DMF medium has been established at room temperature. Rheological analysis was used to investigate the mechanical characteristics of the supramolecular Zn(II)-metallogel. Field emission scanning electron microscopy and transmission electron microscopy were used to analyse the hexagonal shape morphological features of the Zn(II)-metallogel. Interestingly, the electrical conductivity is observed in the electronic device with Zn(II)-metallogel based metal–semiconductor (MS) junctions. All aspects of the metallogel's electrical properties were investigated. The electrical conductivity of the metallogel-based thin film device was 7.38 × 10⁻⁵ S m⁻¹. The synthesised Zn(II)-metallogel based device was investigated for its semi-conductive properties, such as its Schottky barrier diode nature.
