Disentangling Polaron Formation Pathways in Y6 by Probing Noninteracting and Interacting Chromophores via Transient Absorption Spectroscopy

Advanced Materials, EarlyView.
The central role of both electronically interacting and noninteracting chromophores in the photogeneration of charges has been unambiguously identified by ultrafast pump‐probe spectroscopy in thin films of the prototypical non‐fullerene acceptor Y6. Onsager‐like autoionization from higher‐energy excitations on Y6 aggregates is found to control polaron ...

Mapping Correlated Environmental Landscapes in the Fluorescence Response of a Pyrenylated Charge‐Transfer Probe via Data‐Driven Nonlinear Regression

Advanced Materials Interfaces, EarlyView.
A pyrenylated donor–acceptor probe exhibits environment‐dependent fluorescence governed by intramolecular charge transfer, restricted molecular motion, and supramolecular organization. Nonlinear regression accurately reconstructs fluorescence responses to viscosity, temperature, concentration, and pH, while correlated parameter maps reveal hidden ...
