For chiral POPs, the sign of CD spectra for PRBT and PSBT was consistent with that of their monomers, whereas PRBT showed a strong negative first Cotton effect and PSBT exhibited a positive one. However, their first CD band had obviously red shifted from 378 nm for RBT-Br in THF to 401 nm (Figure ), which was also consistent with the red-shifted absorption of POPs originated from the extended π-conjugation in the 3D polymeric scaffold.
