“…Phase and crystallinity of all the samples are studied by XRD measurement. As shown in Figure , peak positions of their XRD patterns are well matched with those of reported MOF Cu 3 (BTC) 2 , ,,, demonstrating the successful synthesis of MOF-199. As the quasi-reactant NaOH is gradually added toward the stoichiometric ratio to the primary byproduct HNO 3 , stronger and stronger diffraction peaks are recorded, indicating increasing content of MOF-199 according to their relative peak strength and calculated yield (Figure [A(a–c)], and Table ).…”

“…The reduced volume of mother liquor also confirms this situation (Table S1). As a possible result, the solvent remaining in the system is not enough to support the complete conversion of the reactant within the same reaction time . Reasonably, the samples MOF-199-4 and MOF-199-8 exhibit gradual decrease in crystallization according to their XRD patterns.…”

“…16 Besides, the big crystal is helpful to achieve high adsorption capacity, which can ascribe to its longer channel than the nanosized one. 28 Additionally, the CO 2 adsorption isotherm is also measured at 298 K for the sample MOF-199-2S to evaluate the isosteric heat of adsorption according to the Clausius−Clapeyron equation. Its isosteric heat of adsorption basically is maintained at 25.2 kJ•mol −1 , implying a physisorption process.…”

“…26,27 Modified slurry crystallization can enhance conversion and yield of MOF-199 by strengthening the supersaturation of the reactants, which also reduce solvent consumption and mother liquor. 28 After incorporating copper-(II) hydroxide into MOF-199, it took 24 h to prepare and additional time to recover by washing with ethanol. One of the remaining problems is how to separate the remaining insoluble copper(II) hydroxide from the solid MOF-199.…”

To eliminate the effect of the byproduct on the yield and mother liquor in synthesizing metal–organic framework (MOF), an alkali-induced self-transferring byproduct (AISB) method is proposed by introducing alkali NaOH as a quasi-reactant which indirectly makes contact with the reactants. The quasi-reactant well captures and immobilizes the byproducts volatilized from mother liquor, simultaneously reducing reaction resistance and improving concentration gradient of reactants and intensifying the crystallization. It is found that ethanol not only acts as a solvent but also is partially oxidized by the primary byproduct HNO3. Thus, the reaction environment with a strong acid is weakened, which is convenient for the formation and existence of MOF-199. It is first confirmed by the appearance of Na2CO3 and NaNO2 in the quasi-byproduct. An improved reaction mechanism of the MOF-199 material is also proposed. Also, the resultant mother liquor can be directly used for next preparation. The reaction rate constant of the AISB method reaches up to 1201.2 mol–1·h–1. A high dry base yield up to 97.3% can be calculated based on the added Cu(NO3)2. Especially, the obtained sample MOF-199-2S shows a specific surface area of 1734 m2·g–1, which is obviously better than the samples obtained from traditional hydrothermal methods. It exhibits a CO2 static adsorption capacity of 9.03 mmol·g–1 at 1.0 bar and 273 K. Its cyclic CO2 adsorption capacity in simulated flue gas flowing through the fixed bed is stable at around 1.25 mmol·g–1 with a small pressure drop of 1.6 bar, which benefits from its large size (0.7 mm). Notably, by replacing the quasi-reactant NaOH with Cu(OH)2, this method provides a sustainable and ingenious strategy to synthesize MOF with zero discharge.

transistors into small areas, enhancing the performance and complexity of integrated circuits (ICs). [1,2] In modern ICs, the complexity becomes visible as the distance between interconnect structures get smaller. [3] Currently, the multilevel interconnect systems employed in CMOS have inter distances below 50 nm, [4] which might compromises the performance of the ICs. The impact rises from the nonzero resistance (R) and the inherent parasitic capacitance (C p ) between neighboring interconnects separated by interlayer dielectrics (ILDs), inducing cross-talk noise, affecting the switching speed and the power consumption of ICs. [5,6] Both R and C p depend on the distance between interconnects and ILD used as an insulating layer. [3] Thus, to continue electronics scaling-down, stateof-the-art strategies have been proposed, focusing on the metals with enhancement conductance (e.g., Cu, Co, and Ru) [7][8][9][10][11][12] and the replacement of traditional dielectrics for different organic materials and porous oxides with low-dielectric-constant (κ < 2.4). [3] While organic materials present low-κ owing to their limited polarizability, the oxide layers have their low-κ caused by large free volumes. [3,13] In both cases, intrinsic disorder and high porosity lead to poor thermal properties, [14][15][16] where heat management is critical. Recently, advances in boron nitride placed 2D materials as a promising class of materials to be considered for low-κ dielectrics. [17,18] However, the The miniaturization of electronic devices highlights the need for robust low-κ materials as an alternative to prevent losses in the performance of integrated circuits. For it, surface-supported metal-organic frameworks (SURMOFs), a class of porous-hybrid materials, may cover such a demand. However, the high-intrinsic porosity makes determining the dielectric properties difficult and promotes the integration of SURMOF thin films. Here, the integration of ultrathin HKUST-1 SURMOF films into a 3D functional device architecture using soft-top electrical contacts is addressed. In this novel approach, the device structure assumes an ultracompact capacitor structure allowing determine the dielectric properties of porous thin films with considerable accuracy. A low-κ value of 2.0 ± 0.5 and robust breakdown strength of 2.8 MV cm −1 are obtained for films below 80 nm. The spontaneous selfencapsulated structure provides a footprint-area reduction of up to 90% and yields good protection for the SURMOF toward different hazardous exposure. Finite-element calculations compare the HKUST-1 performance as dielectric layer with well-established insulators applied in electronics (SiO 2 and Al 2 O 3 ). The possibility of integration and miniaturization of HKUST-1, combined with their interesting insulating properties, place this hybrid material as a robust low-k dielectric for novel electronics.
