Two pillared metal-organic frameworks containing urea functional groups were synthesized by a sonochemical method and characterized by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy and elemental analysis. The time of sonication and concentration of starting materials have been optimized to synthesize nanoparticles of TMU-31 and TMU-32. These two frameworks are interesting candidates for a comparative fluorescence study. Thus, their potential abilities for phenol sensing were investigated. This investigation revealed the prominent roles of hydrogen bond donating urea groups inside the pore cavity in the ability of these structures in phenol sensing.
通过超声化学方法合成了两种含尿素官能团的柱撑金属有机框架，并通过扫描电子显微镜、X射线粉末衍射、红外光谱和元素分析对其进行了表征。优化了超声处理时间和起始原料浓度以合成TMU-31和TMU-32的纳米颗粒。这两种框架是进行比较荧光研究的有趣候选物。因此，研究了它们对苯酚传感的潜在能力。该研究揭示了孔腔内氢键供体尿素基团在这些结构的苯酚传感能力中所起的重要作用。
