“…The state of these polymers dramatically affects their absorbance; in the neutral, reduced state, the absorbance of these polymers blueshifts to the visible range in comparison to that in the oxidized state. 31 The highly negative zeta potentials obtained with both NPs in addition indicate that the NP suspensions have high colloidal stability mediated by interparticle charge repulsion. 32 In fact, the NPs are not able to dissolve in organic solvents in which the monomers would normally be soluble ( Figure S7) because of their interaction with the anionic surfactants.…”
