通过锌对具有AIE活性的席夫碱进行预官能化，合成了一系列具有固态发光和可调谐发光（490 ~ 608 nm）的IRMOF-3骨架。这些前体AIE活性配体赋予功能框架增强的荧光发射效率（从0.16%到1.03%）。IRMOF-3-h显示了花状形态归因于J-聚集体的形成，并且可以用作用于灵敏检测铜（ii）（135 pM）和硫醇（subnanomole）的荧光探针。
A series of functional IRMOF-3 frameworks with solid-state luminescence and tuneable light emission (from 490 to 608 nm) have been synthesized by per-functionalizing AIE-active Schiff-bases with zinc. These precursor AIE-active ligands endowed the functional frameworks with boosted fluorescence emission efficiencies (from 0.16% to 1.03%). IRMOF-3-h revealed a flower-like morphology attributed to the formation of J-aggregates, and could be used as a fluorescent probe for sensitive detection of copper(ii) (135 pM) and thiols (subnanomole).
