Precise Tracking and Modulating Aggregation Structures of Conjugated Copolymers in Solutions

The effects of the backbone shape of the conjugated polymers on the aggregation features in solutions, and further on the morphology in solid states are rarely reported. Herein, four copolymers, BDOPV-T, BDOPV-T0.8-2T0.2, BDOPV-T0.2-2T0.8, and BDOPV-2T, are developed to reveal that the aggregation structures of these polymers are dependent on the special properties of the conjugated backbone. Our investigation demonstrates that the aggregation microstructures of these polymers in solid states are inheritable from those in solutions.
