    • Here the molar extinction is computed based on the concentration of the fluorenyl units, and the difference in the molecular weight of the linear and macrocyclic polymer (due to the presence of a linker in the macrocycle) is accounted for

    • The horseshoe-like structure for the 12-mer was configured by starting with a symmetric 15 transition dipole ring and three adjacent dipoles were removed to form a gap that had an angle equivalent to approximately 2π/5. Molecular modeling of an isotactic 12-mer macrocycle (where the 9,9-dimethylfluorene groups are configured anti with respect to each adjacent unit) predicted that the gap region covered approximately this angle. The anisotropy simulation result in a biexponential decay with two approximately equal amplitude components and time constants differing by a factor of 10.
