The aggregation behaviors of conjugated polymers significantly influence their performance in solution-processed optoelectrical devices. Traditionally, the formation aggregates from self-assembly is considered as a thermodynamic equilibrium process. abundant degree conformation freedom might lead to complex solution. However, energy landscape during has rarely been studied before, which would provide energetic and structural information about different aggregates. Our work tried unravel investigate thermodynamically kinetically stable Herein, naphthalene diimide (NDI)-based are obtained through rational molecular design control. Investigation theoretical calculation, photophysical properties, morphologies demonstrates differences between analysis here insight into relations among structure, morphology, properties at level. This further extends our understanding mechanisms.
