Abstract
Molecular imprinting technology was used to coat polydopamine (PDA) onto MIL-53(Fe) surface by simple self-polymerization. The MIL-53(Fe)@MIP composite with enhanced peroxidase-like activity and specific target recognition function was synthesized and selected to construct a fluorescence sensor to detect metronidazole (MNZ). Since the substrate terephthalic acid was incorporated in the framework of MIL-53(Fe)@MIP, no additional luminescent substrate was required. This avoided the interference of the substrate on the enzymatic detection system and improved the accuracy of the assay. The characteristics of MIL-53(Fe)@MIP composite were investigated and confirmed by systematic analyses. The experimental results proved that the sensor provided satisfactory performances for quantitative determination of MNZ in wide linear range from 1 to 200 μM with low limit of detection as 53.4 nM. Potential interfering substances such as common cations and anions, amino acids, other antibiotics, sugars, and food additive were studied to show negligible effect on the assay, allowing the practical application to different fields including milk and human serum by the standard addition method. The recoveries were obtained between 93.2 and 102%, and the RSD was less than 3%.

Abstract
A new Aluminum metal-organic frameworks(Al-MOF) based on tricarboxylate ligands(L){L = 2,2',2'-([1,3,5]-triazine-2,4,6-triimino)tribenzoic acid)} has been designed and synthesized. It can be served as a platform of multi-responsive fluorescence sensor for Fe3+, Sr2+and SiO32-in water, which is mainly due to the significant enhancement effect of these ions on the fluorescence intensity of Al-MOF. Especially, Fe3+ions are rarely able to induce MOFs fluorescence enhancement. The limit of detection for three kinds of ions is 6.62* 10-6M, 5.37* 10-6M, 6.85* 10-10M respectively. Meanwhile, It can also be used as a multi-response fluorescence probe to detect toluene in DMF solution, limit of detection is 9.16* 10-3M respectively. The structure of Al-MOF was characterized by FTIR,1H NMR, SEM, TAG, PXRD and element analysis. The PXRD showed that the structure of Al-MOF remained the high water stability and pH stability. The application of water samples and vegetables showed that Al-MOF had high sensitive detection for Fe3+ions.

Abstract
Multiemissive sensors are being actively pursued, because of their ratiometric luminescent detection capabilities, which demonstrates better sensitivity and selectivity than conventional single-emission sensors. Herein, we present a trichromatic white-light-emitting metal-organic framework (MOF) composite (Z3) by simultaneously incorporating red/green-emitting Pt/Ru complex cations into porous blue-emitting bio-MOF-1 through post-synthetic modification. With the help of a three-dimensional (3-D) dual-ratiometric luminescence recognition method, and unique turn-on responses of the red emission toward amine compounds (ACs), including NH3 and aliphatic amines, via confinement-induced luminescence enhancement effect, Z3 can work as a dual-ratiometric luminescent sensor for discrimination of 7 out of 11 AC vapors. This work not only provides a new AC sensing mechanism (confinement effect) that can induce a "turn-on" response but also proves that the accuracy and selectivity of composite sensor can be greatly improved through the combination of 3-D recognition method and the confinement effect. Thus, it open up fresh opportunities to develop composite sensors with excellent sensing and differentiating ability.
