Temporal Flux Organization as a Principle for Network-Controlled Self-Assembly

) selectively accelerates late-stage elementary reactions, reorganizing temporal flux, suppressing intermediate accumulation, and generating a strong forward flux toward the final product. As a result, near-quantitative product formation emerges at the network level despite complete molecular reversibility.This Account synthesizes a progression from quantitative kinetic analysis (QASAP), through explicit reaction-network modeling (NASAP), to a network-level understanding of quasi-irreversibility, culminating in temporal flux organization as a design principle for reversible self-assembly. These studies establish temporal flux organization as a unifying principle that links microscopic kinetics to macroscopic self-assembly outcomes in fully reversible reaction networks. By reframing self-assembly as a problem of time-resolved flux flow rather than static pathways or isolated rate constants, network-controlled self-assembly elevates reaction flux from a descriptive quantity to a design variable, enabling predictive and rational control of pathways and yields across coordination assemblies, supramolecular polymers, and other dynamic reaction networks.
