Rodlike π‐conjugated molecules in which two OPV fragments are connected through a diacetylene bond self‐assemble in aqueous and organic media. Optical spectroscopy and AFM measurements indicated that, in water, strong hydrophobic interactions between π‐cores promote aggregation into robust, uniform micellar structures. In contrast, in apolar solvents, a fibrilar morphology is obtained by coiling of columnar stacks. These stacks are formed in a nucleation‐elongation process with degrees of cooperativity of 0.006, that is influenced by the low rotation barriers around the σ‐bonds in the diacetylene linker
