Abstract

The BPy-DDQ charge transfer complex (4,4′ bipyridine with 2,3 dichloro 5,6 dicyano 1,4 benzoquinone) represents a novel class of redox active organic materials with distinctive donor-acceptor interactions and tunable electronic properties. Chronoamperometric studies at gold electrodes revealed moderately fast electron transfer kinetics and stable pseudocapacitive contributions, validating its dual functionality in diffusion-controlled transport and capacitive charge storage. These findings highlight its disruptive potential in supercapacitors, organic batteries, and electrocatalytic systems, offering eco-friendly alternatives to conventional heavy metal electrodes. By bridging molecular level charge transfer dynamics with device level performance, BPy-DDQ contributes directly to green energy storage, pollution reduction, and environmental sustainability, underscoring its transformative role in environmental studies.
