ABSTRACT
Controlling the solution-state aggregation of conjugated polymers for producing specific microstructures remains challenging. Herein, a practical approach is developed to finely tune the solid-state microstructures through temperature-controlled solution-state aggregation and polymer crystallization. High temperature generates significant conformation fluctuation of conjugated backbones in solution, which facilitates the polymer crystallization from solvated aggregates to orderly packed structures. The polymer films deposited at high temperatures exhibit less structural disorders and higher electron mobilities (up to two orders of magnitude) in field-effect transistors, compared to those deposited at low temperatures. This work provides an effective strategy to tune the solution-state aggregation to reveal the relationship between solution-state aggregation and solid-state microstructures of conjugated polymers.
