A novel strategy toward well-defined polyethylene-based cyclic homo/copolymers is presented. Tris(3-(anthracen-9-ylmethoxy)propyl)borane, prepared by hydroboration of 9-((allyloxy)methyl)anthracene with BH, was used to initiate the polyhomologation of dimethylsulfoxonium methylide to afford well-defined anthracene-teminated linear polyethylene (PE). The azido and alkynyl groups at α and ω positions of the PE chain were introduced via the anthracene/maleimide Diels-Alder (D-A) reaction and esterification, respectively. Subsequent intramolecular
