Azide-alkyne click polymerization has become a powerful tool for polymer synthesis. However
the click polymerization between internal alkynes and azides is rarely utilized to prepare functional polymers. In this work
the polymerization reactions of activated internal alkyne monomers of tris(2-butynoate)s (
1
) with tetraphenylethene-containing diazides (
2
) were performed in dimethylformamide (DMF) under simple heating
affording four hyperbranched poly(methyltriazolylcarboxylate)s (
hb
-PMTCs) with high molecular weights (
M
w
up to 2.4 × 10
4
) and regioregularities (up to 83.9%) in good yields. The
hb
-PMTCs are soluble in common organic solvents
and thermally stable with 5% weight loss temperatures up to 400 °C. They are non-emissive in dilute solution
but become highly emissive in aggregated state
exhibiting aggregation-induced emission characteristics. The polymers can generate fluorescent photopatterns with high resolution
and can work as fluorescent sensors to detect nitroaromatic explosive with high sensitivity.
