Exploring novel nickel schiff-base complexes: One-pot green synthesis, density functional theory studies,
and structural investigations toward energy storage applications
Prof. Thathan Premkumar
Four hexa-coordinated Ni(II)-based complexes were synthesized using ketoacid–diaminoguanidine ligands, forming robust 3D supramolecular architectures stabilized by intra- and intermolecular hydrogen bonding. Structural modifications, particularly the incorporation of a methyl group, significantly enhanced the porosity and electrochemical performance of the materials. Among them, the NiL4 complex exhibited the highest specific capacity (202 C/g) and an impressive energy density of 61 Wh/kg in an asymmetric supercapacitor device. These results highlight the strong potential of these materials for next-generation energy storage applications.
