A multistimulus-responsive self-healable supramolecular copper(ii)-metallogel derived from l-(+) tartaric acid: an efficient Schottky barrier diode

Abstract

An ultrasonication-based copper(II)-metallogel synthesis strategy has been developed using copper(II)-source and L-(+)tartaric acid as a low molecular weight gelator (LMWG) in DMF medium. The rheological studies, along with the thixotropic study, established the gel material as mechanically stable and self-healable in nature. The stone-like morphological patterns of Cu(II)metallogel were characterized through a field emission scanning electron microscopic study. The EDX elemental mapping confirms the primary chemical constituents of the metallogel. Besides, the supramolecular assembly of Cu(II)-metallogel displays electrical conductivity on a metal–semiconductor (MS) junction electronic device. The electrical property of the metallogel was thoroughly examined. The semi-conductive characteristics like the Schottky barrier diode nature of the synthesized Cu(II)-metallogel based device were explored.
