a Chemical structure of tetraarylsuccinonitrile (TASN) and its equilibrium with the corresponding C–C-cleaved radicals. b Schematic image of the crystallization of a TASN-centered polymer from its molten state. c Synthetic scheme of TASN-containing linear polycaprolactone (L-PCL), TASN-containing star polycaprolactone (S-PCL), and control polycaprolactones that contain bisphenol A (C1-PCL) or fluorescein (C2-PCL) at the center of the chain.
