Abstract: Controlling the self‐assembly and aggregation behavior of nanographdiyne (NanoGDY) in solution is crucial for understanding the intrinsic structure‐property relationships of graphdiyne. However, capturing the persistent NanoGDY dimer aggregate presents a significant challenge. Herein, we have successfully synthesized a novel ester‐functionalized NanoGDY with solubilized alkyl chains at the periphery named NanoGDY‐CO and investigated its aggregation behavior at different temperatures as well as different solvents by 1 H NMR, UV–vis, and FL spectroscopy. The combination of intermolecular hydrogen bonding formed by the ester groups and π─π stacking facilitates the self‐assembly of NanoGDY‐CO into a persistent coplanar and slip‐stacked dimer. In contrast, the branched 2‐octyldodecyl substituent acts as a steric control agent preventing further aggregation of the self‐assembled NanoGDY dimer. This work offers new insights into understanding and manipulating the self‐assembly behavior of NanoGDYs in solution.
