A poly[(phenylene vinylene)-co-dibenzocyclooctyne] polymer prepared by Wittig polymerization chemistry between dibenzocyclooctyne bisaldehyde [DIBO-(CHO)2] and bis(triethyleneglycol)phenylbis(tributylphosphonium) dibromide is reported. The resulting polymer exhibits moderate molecular weight (Mn: 10.5 kDa, Mw: 21.3 kDa, Ð: 2.02) and is fluorescent. It could be readily functionalized by strain-promoted alkyne-azide cycloadditon with different azides, and fluorescence of the polymer was preserved after functionalization. Grafting azide-terminated 5 kDa poly(ethylene glycol) monomethyl ether chains drastically affected the solubility of the polymer. Cross-linking the polymer with poly(ethylene glycol) that was terminated at both ends with azide groups gave access to a fluorescent organogel that could be dried and reswollen with water to form a hydrogel.

一种水解稳定的含环辛炔聚合物的制备和性能
报道了通过二苯并环辛炔双醛 [DIBO-(CHO)2] 和双（三乙二醇）苯基双（三丁基鏻）二溴化物之间的 Wittig 聚合化学制备的聚 [（亚苯基亚乙烯基）-co-二苯并环辛炔] 聚合物。所得聚合物具有中等分子量（Mn：10.5 kDa，Mw：21.3 kDa，Ð：2.02）并且是荧光的。它可以很容易地通过应变促进的炔烃-叠氮化物环加成与不同的叠氮化物进行功能化，并且在功能化后聚合物的荧光得以保留。接枝叠氮化物终止的 5 kDa 聚 (乙二醇) 单甲醚链极大地影响了聚合物的溶解度。
