^aDetermined by gel permeation chromatography in THF.

^bPDI (polydispersity index) = M_w/M_n.

^cMeasured in DMF.

^dPPB₁ and PPB₂ excitation wavelength 430 nm, PPE excitation wavelength 370 nm in DMF.

^eQuantum yield in DMF measured relative to diphenylanthracene standard.

^fDetermined by ¹H NMR peak integration.

^gNot determined due to low signal to noise ratio of the ¹H NMR signals.

^hM4:M2 ratio 1:1.

ⁱM1:M3 ratio 1:1.
