LTLie TianBeijing Normal University GRGuangliu RanBeijing Normal University SZShixuan ZhengPeking University

Key Points

The main aim is to explore how aggregation and solvent polarity affect symmetry-breaking charge separation in perylene diimide trimers.
Examined the charge separation behavior of perylene diimide trimers.
Analyzed the effects of different solvent polarities.
Assessed aggregation influences on charge separation efficiency.
Higher solvent polarity enhanced charge separation efficiency.
Aggregation led to varying pathways of electron transfer.
Symmetry-breaking charge separation occurred more effectively in specific configurations.

Abstract

Symmetry-breaking charge separation (SB-CS) is a fundamental process in natural photosynthetic systems, serving as the primary trigger for electron transfer and ultimately leading to the formation of a charge separated...
