Abstract The synthesis of 9‐methylanthracenyl glycidyl ether (AnthGE) as a crosslinkable monomer that can be applied in anionic ring opening polymerization is reported. Diblock terpolymers the composition methoxy‐poly(ethylene oxide)‐ block ‐poly(2‐ethylhexyl ether‐ co ‐9‐methylanthracenyl ether) (mPEO‐ b ‐P(EHGE‐ ‐AnthGE) with 10 to 24 wt% AnthGE are synthesized and characterized. Their micellization behavior, well their light‐induced core‐crosslinking via irradiation UV light (λ = 365 nm) studied. results compared studies on dimerization, dimer cleavage UV–C 254 nm), same diblock terpolymer organic solution, small‐molecule model compound 9‐methoxymethylanthracene. Differences 1 H NMR spectra crosslinked or dimerized compounds reaction kinetics dimerization reactions under different conditions suggest possible side for case micelles aqueous solution. These limit reversibility anthracene solutions, even if molecule encapsulated within hydrophobic core polymeric micelle.
