“…39 An intriguing observation was the emergence of a vibrational shoulder at 617 nm, suggesting the formation of some self-assembled structures driven by π−π interactions of thiophene rings. 24 Also, dynamic light scattering (DLS) analysis of an in situ aliquot from the polymerization solution revealed a sharp peak at D h = 342 nm, (10,20), (10,30), (20,20), (20,30), (20,40), and (30, 30) (Table 1, entries 7−13). Their absorption spectra shown in Figure 2d revealed two distinct peaks at 381 and 482 nm, corresponding to PQX and P3PT blocks, respectively.…”
