    • Precisely, the PIC-1 (PIC-2) nanoparticle is composed of PIC and TPB (TFPB) moieties. We verified the binary components by measuring the FT-IR spectra of the precipitated sample. See Supporting Information. In the main text, both of these nanoparticles are called PIC nanoparticles, because their optical properties are dominated by the PIC chromophore.

    • The ionic strength (I) of the solution is given by I, 0:5 ∑(Cizi2, where Ci and z i are the concentration and valency of ion i, respectively, and the summation is taken over all the ions in solution. To prepare PIC-1 nanoparticles under the condition of ρ, 2, for instance, 0.1mL of a PIC-Br aqueous solution (0.1 mM) was added into 0.2mL of a NaTPB aqueous solution (0.1 mM, We assume that 1-1 ion-pair formation of PIC-TPB produces electrically neutral species, such that free ionic species in the solution are unreacted Na, Br, and TPB, Hence, we can estimate the concentration of each ion in solution as follows; CNa, 0.1 -x (2/3, 1/15 mM, CBr, 0.1 -x (1/3, 1/30 mM, CTPB, 0.1 x 1/3, 1/30 mM. Thus, I, 2/3, × 10-4
