“…The bond distance of Cd(II)−N is from 2.332 (5) 177.9(2)°(Table S3), which are in agreement with those of the previous similar Cd(II) complex. 48 As found in Figure S6b, the nearby Cd(II) ions are doubly joined by two CBIA − anions in which two carboxyl groups adopted μ 1 -η 1 :η 1 modes to form a bimetallic ring [Cd 2 (CBIA) 2 ] 2+ , then the adjacent rings are connected by 4,4′-bipy into a 1D cationic cylinder configuration. The hydroxyl and CBIA − anion without coordination act as counterions to balance the positive charge of the framework, the L − anion is inside the channel, and the guest hydroxyl and lattice water are located within the void between the cylinders.…”

“…Preparation of HSF 1. Compound 1 was prepared basically according to the method described in the literature, 48 but it was slightly improved to increase its yield. The main preparation process is as follows: A mixture of HCBIA (11.8 mg, 0.05 mmol), Cd(NO 3 )• 4H 2 O (15.4 mg, 0.05 mmol), 2 mL of H 2 O, and 5 mL of acetonitrile was stirred at 25 °C for 15 min.…”

“…Note that both complexes 1 and 2 have higher water absorption values than those of free HCBIA ligand (82 mg•g −1 ) and complex [Zn(CBIA)Cl] n (93 mg•g −1 ) under the same conditions. 48 Obviously, the high water absorption of these two complexes means that they can construct high-density hydrogen-bond networks at high humidity, which is a prerequisite for their possible strong proton conductivity.…”

“…The presence of 1 and 2 further expand the team of HSFs and CPs with high proton conductivity using zwitterionic ligands, further indicating that zwitterionic ligands are a good choice for the construction of high conductivity. Note that although the preparation and crystal structure of compound 1 has been previously described by Zhang et al, 48 its water stability and proton-conductive properties are studied here for the first time. In addition, their mechanisms are compared and proposed in detail.…”

Finding more metal complexes with outstanding water stability and high proton conductivity still has important research significance for the energy field. Herein, two highly proton-conductive complexes, one hydrogen-bonded supramolecular framework (HSF) [Cd(CBIA) 2 (H 2 O) 4 ]•2H 2 O (1) and one coordination polymer (CP), {[Cd 2 (CBIA) 2 (4,4′-bipy) 2 (H 2 O) 2 ]• (CBIA)•(OH)•2H 2 O} n (2) (4,4′-bipy = 4,4′-bipyridine), were triumphantly assembled using a zwitterionic organic compound, 2-(1-(carboxymethyl)-1H-benzo[d]imidazol-3-ium-3-yl)acetate (HCBIA).In the structure of HSF 1, there are several coordination and lattice H 2 O units except for the two monodentate CBIA − anions. CP 2 with a one-dimensional (1D) cylindrical structure has free CBIA − units and free H 2 O units located in the cavity. Thanks to the ability of the uncoordinated carboxyl groups and coordination/ lattice water molecules to construct the rich H-bonding networks, both complexes exhibit super-high proton conductivities, reaching 5.09 × 10 −3 and 3.41 × 10 −3 S cm −1 under 100 °C/98% relative humidity (RH), respectively. Based on the exploration of crystal structure data, combined with the calculated activation energy, and adsorption/desorption plots of nitrogen and water vapor, the causes and differences in proton conductivity of the two complexes, especially the proton-conductive mechanism, are compared and analyzed. This study again confirms that the zwitterionic ligands can exert important effects on forming organo-inorganic hybrid materials with high proton conductivity.

In recent years, two‐dimensional (2D) materials with unique mechanical, optical, and electrical properties have attracted extensive attention. In terms of mechanical properties, 2D molybdenum disulfide (MoS2) can perform larger strains than traditional semiconductor materials. In this contribution, we used the chemical vapor deposition (CVD) technique to grow MoS2 films on a Si wafer and transfer them onto a flexible substrate. The controlled deformation of 2D MoS2 samples was realized by encapsulating them with a flexible acrylate film via successive spin‐coating and photopolymerization. Improved strain control was achieved due to the perfect integration of different components (MoS2/substrate) and the high adhesion of polymers. This approach provided a better detection of the changing structure of the MoS2 monolayer on the flexible substrate during tensile. It is noted that the crystal symmetry damage caused by strain is reflected in the redshift of the characteristic bands of MoS2. Hence, we provided an effective way for strain regulation of MoS2 for future applications in flexible devices.This article is protected by copyright. All rights reserved.

Modified Molten Salt Assisted Exfoliation of Large‐Size 2D Materials

Abstract2D materials hold great promise for numerous applications, and the physical properties of individual 2D materials depend strongly on their thickness and lateral size. Currently, there is a lack of a straightforward method to produce 2D materials with both high‐quality and ultra‐high aspect ratios. Herein, a modified molten salt‐assisted exfoliation (MMSAE) strategy is proposed to prepare high‐quality 2D materials with large sizes and controllable thickness. The MMSAE approach involves using high‐frequency disturbance to create a shear force that peels off the layers of the intercalated material (e.g., graphene, MoS2, WS2, and clays), resulting in the successful and efficient exfoliation of 2D material. Taking h‐BN for example, the MMSAE approach achieves the preparation of 2D h‐BN with an average lateral size of 6.30 µm, thickness of 2.34 nm, and a high aspect ratio of 2692.
