Tunable Conductivity and Magnetism in Modular Sulfur-Based Coordination Polymers: Fundamentally New Materials for Energy Storage, Computation, and AI
Abstract
The overall objective of this project is to move beyond Òstate of the artÓ capabilities in charge storage, processing, and neuromorphic applications by realizing a fundamentally new class of transition metal-chalcogenide materials. Our approach involves rational control of the electronic and magnetic properties of a family of sulfur-based coordination polymers. Incorporation of sulfur-based linkers in coordination polymers has led to materials with the capacity for tunable conductivity and magnetism. However, these advances are restricted to only a few systems and morphologies as controlled growth of sulfur-based materials is challenging. My group has recently reported the synthesis of new thiol and sulfide-based coordination polymers. In the course of this work we have discovered design principles which enable the modular synthesis of a family of robust sulfur-based materials with tunable electronic and magnetic properties. In Objective I, we will synthesize tunable hybrid transition metal coordination polymers featuring combinations of redox active linkers and mono- or multi-metallic sulfide nodes. We will optimize and control the syntheses of these materials as powders, single crystals, or thin films as required for different characterization and fabrication. In Objective II, we will quantify and rationally tune the electronic and magnetic properties of the new materials by modifying the composition and redox states of nodes and linkers. Similarly, we will explore the interface of conductivity and magnetism, also as a function of the redox-state of the nodes and linkers. In Objective III, we will incorporate transition metal sulfur-based coordination polymers with different properties into analytical assemblies, testing their stability and performance with respect to fabrication conditions. We will quantify the tradeoffs and opportunities for engineering with these new materials.
