Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The construction of amphiphilic polycarbonates through epoxides/CO₂ coupling is a challenging aim to provide more diverse CO₂‐based functional materials. In this report, we demonstrate the facile preparation of diverse and functional nanoparticles derived from a CO₂‐based triblock polycarbonate system. By the judicious use of water as chain‐transfer reagent in the propylene oxide/CO₂ polymerization, poly(propylene carbonate (PPC) diols are successfully produced and serve as macroinitiators in the subsequent allyl glycidyl ether/CO₂ coupling reaction. The resulting ABA triblock polycarbonate can be further functionalized with various thiols by radical mediated thiol–ene click chemistry, followed by self‐assembly in deionized water to construct a versatile and functional nanostructure system. This class of amphiphilic polycarbonates could embody a powerful platform for biomedical applications.</p> </abstract>
