Synthesis, self-assembly, and pH-responsive behavior of (photo-crosslinked) star amphiphilic triblock copolymer

► We synthesized photo-crosslinked star triblock copolymer with pH response. ► The CMC value was dependent upon micelle structure and photo crosslinking degree. ► The micelle size was controlled by photo crosslinking degree and pH value. ► DLS measurement demonstrated the photo crosslinking-controlled pH response.
