The fabrication and characterization of a supramolecular Cu-based metallogel thin-film based Schottky diode

In the present study, a stable supramolecular Cu( ii )-metallogel has been synthesized based on copper( ii ) acetate monohydrate and succinic acid, engineered as a low-molecular-weight organic gelator. The mechanical assets of the Cu-H 4 L metallogel have been explored through a rheological investigation. Further, the aggregation of the synthesized metallogel has been well established via several experiments using Job plots and ESI-MS. Apart from this, the morphology of the synthesized supramolecular metallogel was scrutinized via FESEM, TEM, and AFM studies, revealing the self-assembled thread-like morphology of the Cu-H 4 L metallogel. The functional group, elemental composition, crystalline behaviour, and thermal stability of the Cu-H 4 L metallogel were probed via FT-IR, XPS, P-XRD, and TGA studies, respectively. The optical properties of the Cu-H 4 L metallogel reflected its semiconducting nature. Thus, based on the semiconducting properties of the Cu-H 4 L metallogel, we have successfully fabricated an active electronic device: a 'Schottky diode'. The synthesis of a Cu-H 4 L metallogel and its application in the fabrication of a Schottky diode are illustrated.
