E-mail: fengac@mail.buct.edu.cn, san.thang@monash.edu Experimental Section 1.1 General Information All commercially available reagents and solvents were used without further purification except as indicated below. 2,2'-Azobisisobutyronitrile was recrystallized from methanol. N-isopropyl acrylamide was recrystallized from n-hexane. 1 H NMR spectra were recorded on a Bruker Avance III 400 (400 MHz) spectrometer in DMSO-d 6 . Gel permeation chromatography (GPC) was performed using a Shimadzu GPC system (using low dispersity polystyrene as standard) equipped with 10 μm mixed columns in series and in line with a 20 A refractive index detector. DMAc was used as eluent at a flow rate of 1 mL/min. Fluorescence experiments were carried out on a Hitachi F-4600 fluorescence spectrophotometer. The excitation wavelength was 339 nm, the excitation slit was 5 nm, and the emission slit was 2.5 nm with a scanning speed of 500 nm/min. UV-vis spectra were recorded on a Hitachi U-3900H UV-vis spectrophotometer. The micromorphology of self-assemblies were observed by a Hitachi HT7700 transmission scanning electron microscopy (TEM). Circular dichroism (CD) spectrum was recorded on a Jasco-810 spectropolarimeter. 1.2 Synthesis of the RAFT Agent-DTTCP HO S S C 12 H 25 O CN S Electronic Supplementary Material (ESI) for ChemComm.
