| Abstract |
The effects of synthetic methods, modulator types, the content of the modulator, and reaction time on
the size and morphology of a microscale Zn-MOF containing dual Lewis basic amino and carbonyl
groups, namely [Zn(NH2-bdc)(4,4’-bpy)] {NH2-H2bdc = 2-amino-1,4-benzenedicarboxylic acid and 4,4’-
bpy = 4,4’-bipyridine}, were systemically investigated. Uniform octahedral microparticles of Zn-MOF with
an average size of 1.7 µm were obtained within an hour at ambient temperature under ultrasound
irradiation using sodium acetate as a modulating agent. Interestingly, Zn-MOF has been demonstrated for
the dual-functional fluorescent detection of Al3+ and methanol based on a fluorescent turn-on strategy.
Very low detection limits (LODs) for Al3+ and methanol were achieved using microcrystalline Zn-MOF and
reached 30 nM and 0.7% (v/v), respectively. In comparison to the larger size of the polycrystalline ZnMOF, the microparticles obtained from the ultrasonic route exhibited an improvement in the detection
sensitivity. The dual uncoordinated Lewis basic sites play an important role in the sensitivity and selectivity
of the detection. Additionally, the fluorogenic change in the sensing process can be observed by the
naked eye under UV-light, allowing preliminary on-field screening. |
