Supramolecular well‐defined nano‐microstructures are grown much interest in both scientific and technological interest due to their applications in nano‐ and bio‐techalogical research. In this report, we described synthesis of amphiphilic naphthalenediimide (NDI) derivative ( 1 ) bearing melamine (MM) head group and studied its self‐assembly with solvophobic control. Interestingly, derivative 1 produces well‐defined flower‐like supramolecular structure in THF/hexane solvent mixture. Furthermore, SEM imaging used to visulaise step‐wise growth of flower‐like assembly. The formation of flower‐like supramolecular assembly is attributed to π‐π stacking of the NDI core, along with hydrophobic interactions of an alkyl chain along with H‐bonding of the melamine head group. We believe such arrangement within the molecule prevent crystalisation and favour the directional growth of flower‐like streuctures. The self‐assembled flowers exhibit porous structures similar to natural flowers, and may find practical applications in the field of optoelectronic materials, mimicking enzyme catalysis and biosensors.
