Metal-Ion-Mediated Supramolecular Chirality for Enantioselective Catalysis and Molecular Recognition

Abstract

Metal-ion-mediated supramolecular chirality represents a powerful paradigm for creating adaptive, functional materials that drive enantioselective catalysis and high-fidelity molecular recognition. While significant progress has been achieved at the molecular scale, translating these principles into robust, scalable, and equitable socio-technical systems demands a comprehensive systems-level perspective that integrates architecture design, process engineering, computational intelligence, governance frameworks, and sustainability metrics. This paper offers an extended analysis of the structural trade-offs, hierarchical assembly architectures, and dynamic amplification mechanisms that govern chiral induction in metal-coordinated supramolecular networks. We examine how these architectures can be embedded within continuous-flow catalytic reactors, sensor arrays, and separation modules to achieve intensified, sustainable production of enantiopure compounds. The discussion extends to the role of machine learning and autonomous experimentation in navigating vast chemical spaces and optimizing multiscale chirality transfer. Crucially, we position these technological advances within broader regulatory, economic, and ethical contexts, addressing intellectual property landscapes, regulatory harmonization for chiral pharmaceuticals, circular economy mandates for critical metals, and equitable access to life-saving enantiopure medicines. Throughout, the paper emphasizes that realizing the full societal benefit of metal-ion-mediated chiral systems requires co-designing molecular architectures with the infrastructures of manufacturing, digital governance, and policy, thereby forging a resilient innovation ecosystem that is as much about structural chemistry as it is about systemic responsibility.
