“…Subsequently, PEO 45 -PETTC was used as a macroCTA to mediate the RAFT dispersion copolymerization of BzMA and PyAMA in an ethanol/water mixture (w/w = 80/20), and the target DP of the solvophobic block P(BzMA n - co -PyAMA (1– n ) ) x (wherein the subscript numbers are the proportions of BzMA units and PyAMA units, x represents the target DP of solvophobic block) was set as 20, 30, 40, 100, and 150, respectively. Using PEO as solvophilic block and BzMA as core forming monomer is a classic PISA formulation to produce polymer nano-objects with various morphologies, including micelles, nanowires, and vesicles; − thus, it was used in this study. In order to explore the effect of the amount of PyAMA on the fluorescence emission of the obtained nanoparticles, the feed molar ratio of PyAMA/BzMA was set as 0/100, 1/99, 2/98, 2.5/97.5, 3/97, and 3.5/96.5.…”
