Organic Photovoltaics: Understanding the Preaggregation of Polymer Donors in Solution and Its Morphological Impact.
Tonghui Wang,Jean-Luc Brédas +1 more
TL;DR: In this paper, a combination of thermodynamic analyses, molecular dynamics simulations, and long-range corrected density functional theory calculations enables us to establish the Flory-Huggins interaction parameter, χ, as a useful figure of merit that allows us to integrate the contributions from all inter-related molecular interactions and to describe the extent of polymer preaggregation in solution at room temperature.
