Developing　simple　methods　to　prepare　non-traditional　intrinsic　luminescent　(NTIL)　polymers　with　enhanced　thermal　property　are　very　urgent,　interesting　and　important.　Here,　we　demonstrate　a　one-pot　method　to　design　NTIL　polymer　with　improved　thermal　property　by　introducing　phenyl　ether　group　into　the　molecular　design　of　triphenylmethanol-containing　polymers　via　Barbier　polymerization-induced　emission　(PIE).　Through　Barbier　polymerization　of　4,4′-dibromodiphenyl　ether　and　peroxyesters　in　tetrahydrofuran　at　80　°C,　a　series　of　phenyl　ether　containing　polymers　have　been　prepared,　including　poly　(phenylether-triphenylmethanol)　(PPTPM),　poly　(phenylether　para-methyl-triphenylmethanol)　(PPMTPM),　poly　(phenylether　para-methoxy-triphenylmethanol)　(PPMeOTPM).　Interestingly,　these　polymers　exhibit　aggregation-induced　emission　(AIE)　type　NTIL　characteristics.　By　introducing　functional　phenyl　ether　group　into　polymer　design,　the　thermal　property　of　these　polymers　gets　improved,　where　the　decomposition　temperature　at　5%　weight　loss　(T5)　increases　from　196　to　288　°C,　in　comparison　with　that　without　phenyl　ether　group.　This　work　therefore　opens　a　simple　and　one-pot　avenue　for　the　preparation　of　AIE　type　NTIL　polymers　with　improved　thermal　property,　which　might　cause　inspirations　to　different　fields　such　as　polymerization,　NTIL　and　AIE.　©　2024　Elsevier　B.V.
