摘要

在此合成了三种新的 LMOFs，即[Cd(TPPE)0.5(oba)(H2O)]n（LMOF-1）、[Cd2(TPPE)(bpdc)2]n（LMOF-2）、[Cd2(TPPE)(sdc)2]n（LMOF-3）（TPPE=1,1,2,2-四[4-(吡啶-4-基)苯基]乙烯，oba=4、4'-二苯醚二羧酸，bpdc=4,4'-联苯二羧酸，sdc=4,4'-苯乙烯二羧酸），量子产率高达 43.74%、36.68% 和 45.89%，超过了大多数已报道的镉基 LMOF。这三种 LMOF 对 Fe3+、CrO42- 和 Cr2O72- 都具有良好的检测灵敏度。令人惊讶的是，Na+很少能显著增强 LMOF-3 的荧光强度，其检测限为 1.90×10-5 M。所有这些结果都表明，这三种 MOFs 在荧光粉材料和荧光化学传感器检测水中离子方面具有广阔的发展前景。

Three new AIE-cored luminescent Cd-based MOFs with high quantum yields and selective detection of ions in aqueous media†

Herein, we synthesized three new LMOFs, [Cd(TPPE)_0.5(oba)(H₂O)]_n (LMOF-1), [Cd₂(TPPE)(bpdc)₂]_n (LMOF-2), and [Cd₂(TPPE)(sdc)₂]_n (LMOF-3) (TPPE = 1,1,2,2-tetra[4-(pyridin-4-yl)phenyl]ethylene, oba = 4,4′-diphenyl ether dicarboxylic acid, bpdc = 4,4′-biphenyl dicarboxylic acid, sdc = 4,4′-styrene dicarboxylic acid), with high quantum yields of 43.74%, 36.68% and 45.89%, respectively, exceeding those reported for most Cd-based LMOFs. All three LMOFs have good detection sensitivity for Fe³⁺, CrO₄²⁻ and Cr₂O₇²⁻. Surprisingly, Na⁺ can rarely but significantly enhance the fluorescence intensity of LMOF-3, and the detection limit is 1.90 × 10⁻⁵ M. This is the first reported LMOF material that can quantitatively analyze Na⁺ among references. All results indicate that the three MOFs can be developed into phosphor materials and fluorescent chemical sensors for detecting ions in water.
