derived from a polyhedral oligomeric silsesquioxane (POSS) intermediate and an aggregation-inducedemission (AIE) luminogen tetraphenylethene (TPE) derivative has been synthesized and structurally characterized by various methods. This unique HOF exhibits a permanent porosity with a Brunauer–Emmett–Teller (BET) surface area of 101.9 m2 g−1. This HOF could be well dispersed in organic solvents in the
已经合成了由多面体低聚倍半硅氧烷(POSS)中间体和聚集诱导发射(AIE)发光四苯乙烯(TPE)衍生物衍生的微孔氢键有机骨架(HOF),并通过各种方法对其结构进行了表征。这种独特的HOF表现出永久的孔隙度,布鲁诺尔-埃默特-泰勒(BET)表面积为101.9 m 2 g -1。该HOF可以以几百纳米的大小的纳米颗粒的形式很好地分散在有机溶剂中。这些纳米颗粒在有机溶液中具有高荧光性,并且对铜离子具有高荧光猝灭选择性。此外,该HOF的荧光可以通过添加氰化物时除去铜离子来恢复,而且更有趣的是,该过程可以重复几次,而不会显着牺牲对铜离子的感测活性。
