The cyclotriphosphazene-substituted diazoacetate homopolymer (polyPNDA′) (PNDA′ = hexaphenoxy-substituted phosphazene-containing methylene) and a novel poly(substituted methylene) block copolymer, polyPNDA′-block-poly(hexyloxycarbonylmethylene) (polyPNDA’-b-polyHDA′), were synthesized, and the self-assembly behavior of these polymers was studied in detail. A hexagonally packed aggregated structure was observed in the self-assembled structure of polyPNDA′, whereas a lamellar structure was observed in the microphase-separated nanoassembly of polyPNDA′-b-polyHDA′. These results indicate that a hierarchical structure composed of highly regular polyPNDA′ nanoaggregates and the long-range microphase-separated polyPNDA′ and polyHDA′ domains had formed.

使用含环三磷腈的聚(取代亚甲基)嵌段共聚物自组装分层结构

环三磷腈取代的重氮乙酸酯均聚物 (polyPNDA') (PNDA' = 含六苯氧基取代的磷腈的亚甲基) 和新型聚(取代的亚甲基) 嵌段共聚物 polyPNDA'-嵌段-聚(己氧基羰基亚甲基) (polyPNDA'- b -polyHDA' ),合成,并详细研究了这些聚合物的自组装行为。在polyPNDA'的自组装结构中观察到六方堆积的聚集结构,而在polyPNDA'- b - polyHDA'的微相分离纳米组装中观察到层状结构。这些结果表明,形成了由高度规则的polyPNDA'纳米聚集体和长程微相分离的polyPNDA'和polyHDA'结构域组成的分层结构。
