    isostructural lanthanide metal–organic frameworks (LnMOFs). The as-prepared LnTPTC-2OMe and LnTPTC-2Me were structurally elucidated by means of single-crystal and powder X-ray diffraction in addition to thermogravimetric analysis and were assessed as luminescence ratiometric thermometers by obtaining the temperature dependence of the luminescence behaviors. We found that both the single lanthanide EuTPTC-2OMe

    Three isostructural metal‐organic frameworks (MOFs) based on dicopper paddlewheels and dimethyl‐functionalized linear diisophthalate ligands were solvothermally constructed, with the aim to investigate their performance regarding acetylene (C2H2) storage as well as separation and purification and to further understand the positional effect of the weakly polarized methyl functionality.

    emits ligand fluorescence due to the efficient energy back-transfer of Dy3+ to the ligand, thus allowing accurate non-invasive determination of temperature by different modes. In particular, the TCEL-based emissions of the Dy3+ ions give ideal signals for measuring the temperature in the 303–423 K range. The emissions of the ligand and Dy3+ (4F9/2 → 6H13/2) are used for temperature sensing in the range
    长期以来,人们一直在寻找具有多种操作模式的高性能发光 MOF 温度计,但仍然是一项艰巨的挑战。在这项工作中,我们首次提出了一种基于单镧系金属有机骨架 (MOF) DyTPTC-2Me (H 4 TPTC -2Me = 2',5'-二甲基-[1, 1':4',1”-三联苯]-3,3”,5,5”-四羧酸)。它不仅具有 Dy 3+的特征发光,其中包括从4 I 15/2和4 F 9/2状态(热耦合能级,TCEL)的原子跃迁,而且由于有效能量而发射配体荧光Dy 3+的反向转移到配体,从而允许通过不同模式准确无创地测定温度。特别是,基于 TCEL 的 Dy 3+离子发射为测量 303–423 K 范围内的温度提供了理想的信号。配体和Dy 3+ ( 4 F 9/2 → 6 H 13/2) 用于 423 至 503 K 范围内的温度传感。这两种模式都具有良好的测温性能,包括高相对灵敏度、高温分辨率和出色的
  • High Capacity Hydrogen Adsorption in Cu(II) Tetracarboxylate Framework Materials: The Role of Pore Size, Ligand Functionalization, and Exposed Metal Sites

    A series of isostructural metal-organic framework polymers of composition [Cu-2(L)(H2O)(2)] (L=tetracarboxylate ligands), denoted NOTT-nnn, has been synthesized and characterized. Single crystal X-ray structures confirm the complexes to contain binuclear Cu(II) paddlewheel nodes each bridged by four carboxylate centers to give a NbO-type network of 6(4).8(2) topology. These complexes are activated by solvent exchange with acetone coupled to heating cycles under vacuum to afford the desolvated porous materials NOTT-100 to NOTT-109. These incorporate a vacant coordination site at each Cu(II) center and have large pore volumes that contribute to the observed high H-2 adsorption. Indeed, NOTT-103 at 77 K and 60 bar shows a very high total H-2 adsorption of 77.8 mg g(-1) equivalent to 7.78 wt% [wt% = (weight of adsorbed H-2)/(weight of host material)] or 7.22 wt% [wt% = 100(weight of adsorbed H2)/(weight of host material + weight of adsorbed H-2)]. Neutron powder diffraction studies on NOTT-101 reveal three adsorption sites for this material: at the exposed Cu(II) coordination site, at the pocket formed by three Cu-2} paddle wheels, and at the cusp of three phenyl rings. Systematic virial analysis of the H2 isotherms suggests that the H2 binding energies at these sites are very similar and the differences are smaller than 1.0 kJ mol(-1), although the adsorption enthalpies for H-2 at the exposed Cu(II) site are significantly affected by pore metrics. Introducing methyl groups or using kinked ligands to create smaller pores can enhance the isosteric heat of adsorption and improve H-2 adsorption. However, although increasing the overlap of potential energy fields of pore walls increases the heat of H-2 adsorption at low pressure, it may be detrimental to the overall adsorption capacity by reducing the pore volume.
