Benzene-sulfonohydrazide (ECMMBSH) Schiff base has been made available in an excellent yield via reflux dehydrate of 4-methylbenzene-sulfonohydrazide with 9-ethyl-9H-carbazole-3-carbaldehyde in EtOH. The synthesis of the ECMMBSH was monitored via two main spectroscopic techniques FT-IR and UV-vis tools; ECMMBSH was characterized via MS, ¹H-NMR, FT-IR, CHN-EA, TG/DTG, EDX, and UV-vis., analysis. Moreover, DFT-optimized, Molecular Electrostatic Potential (MEP) and MAC/NPA-charge models were performed for ECMMBSH. The HOMO/LUMO and Density of State (DOS) calculated energy levels were compared to Tuac experimental optical energy gap values in methanol. Additionally, the TD-DFT and UV-vis. experimental absorption behavior was matched under the same condition. Moreover, the chemo-sensation effect of the ECMMBSH towered Cu²⁺ ions via complexation was evaluated by naked eye in addition to the UV-vis spectrophotometric measurements.
