Red means go : The dense π stacking of thiophene‐fused bithiophene derivatives in the crystalline state led to significantly red‐shifted absorption and fluorescence bands (see the photograph of one compound in solution and in the solid state under UV irradiation). The π‐stacking structure could be altered by changing the orientation of one of the fused thiophene rings.
