Conjugated rod molecules bearing flexible coil polymer moieties on both ends self‐organize into 1D or 2D structures, and eventually into a 3D tetragonal superlattice (see Figure), depending on the number of monomeric units in the coils. The 3D ordered rods exhibit a highly extended fluorescence lifetime over the 1D or 2D arrays, making synthetic control of the rod‐to‐coil volume fraction a viable strategy to regulate photophysical properties.
