chloride. We observed the self-assembly of lamellar structures from the complexation of a thymine (T)-functionalized polybenzoxazine (PA-T) with OBA-POSS, stabilized through complementary multiple hydrogen bonding interactions between the T groups of PA-T and the A groups of OBA-POSS. In addition, incorporating POSS presenting multiple, strong, complementary hydrogen bonding A units into the PA-T matrix
我们通过A与辛基(苄基氯)POSS(OVBC-POSS)的反应制备了八重腺嘌呤(A)-官能化的多面体低聚倍半硅氧烷[(octakis(乙烯基苄基腺嘌呤-甲硅烷氧基)倍半硅氧烷,OBA-POSS]纳米颗粒。八(二甲基甲硅烷氧基)倍半硅氧烷(Q 8 M 8 H)与乙烯基苄基氯。我们观察到由胸腺嘧啶(T)-官能化的聚苯并恶嗪(PA-T)与OBA-POSS的络合形成的层状结构的自组装,通过PA-T的T基团和A基团之间的互补多个氢键相互作用来稳定OBA-POSS。另外,通过差示扫描量热法和热重分析法证明,将具有多个,牢固的,互补的氢键合A单元的POSS掺入PA-T基质中,可显着增强该聚合物的热稳定性。
