Supramolecular organic polymer gel formation of a highly crystalline and fluorescent π‐conjugated alternating copolymer, poly(1,2,4,5‐tetrafluorophenylene‐alt‐3,3′‐dihexyl‐2,2′‐bithiophene), occurred in various solvents, and the macrostructure and fluorescence properties of the gel could be directly controlled by the choice of the solvent. The polymer self‐assembled into a spherical form that exhibited red‐colored fluorescence in a non‐aromatic solvent (1,2‐dichloroethane) and into a fibrous form that exhibited yellow‐colored fluorescence in an aromatic solvent (mesitylene).
