Supramolecular design as a route to high-performing organic electrodes.

Organic electrodes may someday replace transition metals oxides, the current standard in electrochemical energy storage, including those with severe issues of availability, cost, and recyclability. To realize this more sustainable future, a thorough understanding of structure-property relationships and design rules for organic electrodes must be developed. Further, it is imperative that supramolecular interactions between organic species, which are often overlooked, be included in organic electrode design.

An Insight into the Interface through Excited-State Carrier Dynamics for Promising Enhancement of Power Conversion Efficiency in a Mn-Doped CdZnSSe Gradient Alloy.

To explore the significance of impurity doping in power conversion efficiency, quaternary gradient CdZnSSe alloy nanocrystals (NCs) and its Mn-doped analogues were synthesized by high-temperature pyrolysis. The undoped and Mn-doped CdZnSSe alloy NCs have been characterized by employing high-resolution TEM, X-ray diffraction, energy-dispersive X-ray spectroscopy, and electron paramagnetic resonance spectroscopy measurements. A low-temperature injection of chalcogens led to a gradient interface in the alloy, comprised of a CdSe/CdS/ZnSe/ZnS nanostructure.
