A new [3 + 3] trimeric macrocycle, based on tetraphenylethylene having an aggregation-induced emission effect, could form a interdigitation molecular cage with a big void by host-guest interactions. The cage could accommodate two TNT molecules and detect TNT at the 1.7 fg level per mL of air. Moreover, the cage could give permanent pores that had a BET surface area of 347 m/g and could adsorb 7.8 wt % CO with high CO/N selectivity up to 32 (273 K, 1 bar).
一种新型的[3+3]三聚体大环,基于具有聚集诱导发光效应的四苯乙烯,通过主客体相互作用可以形成具有大空腔的交错分子笼。该笼可以容纳两个 TNT 分子,并在每毫升空气中检测到 1.7 fg 级别的 TNT。此外,该笼可以提供具有 347 m/g BET 表面积的永久孔,并可以在 273 K 和 1 巴的条件下吸附 7.8wt%的 CO,具有高达 32 的高 CO/N 选择性。
