Qualitative Prediction

The tube theory has made a detailed description for the linear polymer entangled system, while the behavior of entangled star polymers is still determined by a qualitative prediction. In this paper, the dynamical simulation of a three-arms star polymer in the grid model is presented. We record the diffusion coefficient [Formula: see text], the relaxation time for the arms of star polymer [Formula: see text] and some other parameters corresponding to different branch length. Therefore, results that are inconsistent with the theoretical begin to emerge.

We present a new family of porphyrin-functionalized coordination star polymers prepared through combination of coordination-driven self-assembly and post-assembly polymerization. Their self-assembly behaviour in water and potential for photodynamic therapy were demonstrated.
