Herein, we synthesized pillar[6]arene derivatives having alternate methylene and nitrogen bridges. Owing to the charge transfer emission, the solid-state photoluminescence quantum yield (ΦPL) was enhanced compared with that of the parent pillar[6]arene (ΦPL=0.063→ΦPL=0.36). Furthermore, it displayed a turn-off sensing toward nitrobenzene (NB) vapor; a fluorescence quenching was observed when exposed
在此,我们合成了具有交替亚甲基和氮桥的柱[6]芳烃衍生物。由于电荷转移发射,固态光致发光量子产率(Φ PL )比母柱[6]芳烃(Φ PL =0.063→Φ PL =0.36)有所提高。此外,它还表现出对硝基苯 (NB) 蒸气的关闭感应;当暴露于 NB 蒸气时观察到荧光猝灭。
