^aDetermined by GPC (against polystyrene standards) in chlorobenzene at 85 °C.

^b λ _max in chlorobenzene solution.

^cSpin-coated from chlorobenzene solution onto a glass surface.

^d E _HOMO/E_LUMO = [−(E_onset − E_onset (FC/FC⁺vs. Ag/Ag⁺)) − 4.8] eV, where 4.8 eV is the energy level of ferrocene below the vacuum level and the formal potential E_onset(FC/FC⁺vs. Ag/Ag⁺) is equal to 0.45 V.

^eElectrochemical bandgap: E^el_g = E_ox/onset − E_red/onset.

^fOptical bandgap: Eg^opt = 1240/λ_edge.

^gCalculated by using Bragg's Law d = λ/(2 sin θ), where λ = 1.5406 Å. (—) Non-observable.
