Achieving the full control over the production as well as processability of high‐quality graphene represents a major challenge with potential interest in the field of fabrication of multifunctional devices. The outstanding effort dedicated to tackle this challenge in the last decade revealed that certain organic molecules are capable of leveraging the exfoliation of graphite with different efficiencies. Here, a fundamental understanding on a straightforward supramolecular approach for producing homogenous dispersions of unfunctionalized and non‐oxidized graphene nanosheets in four different solvents is attained, namely N‐methyl‐2‐pyrrolidinone, N,N‐dimethylformamide, ortho‐dichlorobenzene, and 1,2,4‐trichlorobenzene. In particular, a comparative study on the liquid‐phase exfoliation of graphene in the presence of linear alkanes of different lengths terminated by a carboxylic‐acid head group is performed. These …
