Inside Front Cover: Excited State Structure and Decay Rates for Aggregates
This work presents a novel definition of exciton coherence length, establishing a unique correlation with the radiative decay rate and resolving previous ambiguities. Three-state model and four-state model reveal how intensity borrowing enables emissive H-aggregates. A molecular descriptor is proposed for optimizing both PLQY and mobility, along with a modified energy gap law identifying an optimal J to minimize non-radiative decay loss (e70013).
