Anisotropic Band-Edge Absorption of Millimeter-Sized Zn(3-ptz)2 Single-Crystal Metal–Organic Frameworks

“…27 This anisotropic optical response near the band edge is expected, given the large birefringence of the MIRO-101 crystal lattice. 53 In order to understand the lower energy band gap described in Figure 1c, we carried out a systematic study of the size dependence of the band-edge absorption spectrum for MIRO-101. We prepared individual single crystals with top view surface areas in the range of 5−37 mm 2 , as measured by optical imaging.…”

Sequential design of adsorption simulations in metal–organic frameworks

“…The design flexibility of MOFs has resulted in their deployment for energy storage, catalysis, drug delivery, photonics, sensors, etc. [2][3][4][5][6][7][8][9][10] Despite the potential of these materials and their increasing numbers in experimental and synthetic studies, there is a challenge to determine which are the best materials and what are the conditions (e.g., temperature, pressure) that maximize their performance.…”

Carbon support tuned electrocatalytic activity of a single-site metal–organic framework toward the oxygen reduction reaction

“…As an emerging class of periodically ordered porous crystalline materials, metal-organic frameworks (MOFs) have attracted extensive attention from interdisciplinary fields and been widely employed in a myriad of applications including gas storage and separation, [1][2][3] optoelectronics, photovoltaics, [4][5][6] sensing, [7][8][9][10] biomedicine, [11][12][13][14] catalysis, [15][16][17][18][19] and energy storage and conversion, [20][21][22][23][24] due to their excellent properties such as structural diversity, tunability and flexibility, and chemical tailorability. Moreover, atomically dispersed metal sites provide a versatile platform for the design and fabrication of MOF-based single-site catalysts, [25][26][27][28] holding tremendous potentials in the field of electrocatalysis from multiple perspectives: 1) abundant metal ions or clusters and ligands allow the design and synthesis of multifunctional MOFs for driving diverse reactions; 2) long-range ordered, tunable and accessible pores provide mass transport channels for the electrolytes or reactants; 3) the well-aligned assemblies of organic linkers and inorganic nodes render MOFs with distinct physiochemical properties unprecedented in conventional materials; 4) single active sites embedded in MOFs make it easier to tailor the electronic structures and investigate the catalytic mechanism.…”
