Fig. 2. Characterizations of P-M: partial ¹H NMR spectra (400 MHz, room temperature) of (a) M, (b) P and (c) P-M in toluene-d₈. The tiny peaks without labels are assigned to satellite peaks from the solvent. AFM images of (d) M, (e) P and (f) P-M spun from toluene solution, respectively. Scale bar: 100 nm.
