? Dendronized cyclic polymers enable modular
preparation of carriers with control of ring
circumference, rigidity, and solubility
Hydrophobic Core
Hydrophilic Corona
? Linear dependence of guest solubility with
host concentration suggests polymers act as
unimolecular micelles effective even at high
dilution
Pyrene
Structure of dendronized cyclic polymer
? Cyclic polycaprolactone provides a
biocompatible biodegradable substrate, that
demonstrates a retarded degradation profile
relative to linear analogues
