Novel amphiphilic block copolymers containing the anthracene unit in the main chain are synthesized by reversible addition‐fragmentation chain transfer (RAFT) polymerization of a cyclic monomer, 10‐methylene‐9,10‐dihydroanthryl‐9‐spirophenylcyclopropane (MDS). A hydrophilic macro‐chain transfer agent is prepared by RAFT polymerization of 2‐hydroxyethyl acrylate (HEA). The polymerizations of MDS using the poly(HEA) afford amphiphilic block copolymers, in which the hydrophobic poly(MDS) segment has a perfectly alternating structure composed of an anthracene unit and a styrene unit, owing to the ring‐opening polymerization system. Characteristic assembled structures and optoelectronic properties of the amphiphilic block copolymers are investigated in various selective solvents.
