Abstract A supramolecular Mn(II)-metallogel (Mn-TA) of profound functionality has been achieved through mixing and subsequent constanct ultrasonication of Manganese(II) acetate tetrahydrate and terephthalic acid, acting as a low molecular weight gelator (LMWG), in N,N-dimethyl formamide solvent medium. The cube like microstructural features were resolved from HAADF STEM imaging. Intersetingly we observe cubic Mn phase inside this supramolecule. The mechanical flexibility of the supramolecular Mn-TA metallogel has been explored through rheological investigations by monitoring storage modulus and loss modulus with respect to angular frequency and shear strain. Metallogel formation strategy of the Mn-TA metallogel have been explored.The electrical property of the metallogel was thoroughly examined and this measurement indicates the semiconducting nature with considerable electronic charge transportation phenomena and promising ON/OFF ratio of Mn-TA metallogel mediated metal–semiconductor (MS) junction device. Based on its conducting property, Mn-TA metallogel was successfully applied to metal–semiconductor junction based Schottky diode.
