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

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. A low molecular weight gelator l -(+) tartaric acid- based self-healing supramolecular Cu( ii )-metallogel offers an electronic device of Schottky barrier diode at room temperature.
