“…UV-Vis spectrum of the LB film (1 layer) showed a welldefined and intense absorption peak at 227 nm (Figure 5). This results from the overlapping of the two observed peaks on MeOH solutions (233 and 246 nm) and can be assigned to π-π* transitions on the 1,3,5-benzenetricarboxylate rings [28,29]. The GIXRD patterns of the drop-cast and LB/LS films (Figure 6) show the characteristic pattern of MIL-96(Al) in agreement with the theoretical pattern [19,20].…”

This contribution reports the fabrication and characterization of ultrathin films of nanoparticles of the water stable microporous Al tricarboxylate metal organic framework MIL-96(Al). The preparation of MOF dispersions in chloroform has been optimized to obtain dense monolayer films of good quality, without nanoparticle agglomeration, at the air-water interface that can be deposited onto solid substrates of different nature without any previous substrate functionalization. The MOF studied shows great interest for CO capture because it presents Al Lewis centers and hydroxyl groups that strongly interact with CO molecules. A comparative CO adsorption study on drop-cast, Langmuir-Blodgett (LB) and Langmuir-Schaefer (LS) films using a Quartz Crystal Microbalance-based setup (QCM) has revealed that the CO uptake depends strongly on the film fabrication procedure and the storage conditions. Noteworthy the CO adsorption capacity of LB films is increased by 30% using a simple and green treatment (immersion of the film into water during 12 h just after film preparation). Finally, the stability of LB MOF monolayers upon several CO adsorption/desorption cycles has been demonstrated, showing that CO can be easily desorbed from the films at 303 K by flowing an inert gas (He). These results show that MOF LB monolayers can be of great interest for the development of MOF-based devices that require the use of very small MOF quantities, especially gas sensors.

“…Compared with MOFs and COFs, HOFs are formed through the interaction of hydrogen-bonding forces. − HOFs have high proton conductivity but poor stability for the weak hydrogen bonds. − Therefore, this shortcoming limits their use under high-temperature conditions. Selective introduction of guest molecules , can increase the number of hydrogen bonds and the stabilities of HOFs. − The large number of hydrogen-bond networks inside HOFs play a key role in the stability of the structure and proton conduction. − Therefore, it is particularly important to improve the proton conduction characteristics and stabilities of these materials. − …”

On the basis of the carboxylic structure of trimesic acid (TMA) and 5-borono-1,3-benzenedicarboxylic acid (B-BDC), here two hydrogen-bonded organic frameworks (HOFs), HOF 1 (MA-TMA) and HOF 2 (MA-B-BDC), were prepared by reacting melamine (MA) with trimesic acid and 5-borono-1,3-benzenedicarboxylic acid, respectively. The as-prepared HOF 1 and HOF 2 with 3D supramolecular structure exhibit excellent performance in proton transport. AC impedance test shows that the proton conductivities of HOF 1 and HOF 2 reach 3.11 × 10 −4 S•cm −1 (343 K, 98% RH) and 4.32 × 10 −4 S•cm −1 (323 K, 98% RH), respectively. To increase the proton conductivity, Im@HOF 1 and Im@HOF 2 were obtained by introducing imidazole (Im), which acts as a jumping site for proton transfer. The proton conductivities of Im@HOF 1 and Im@HOF 2 reached 4.12 × 10 −4 S•cm −1 (333 K, 98% RH) and 1.20 × 10 −3 S•cm −1 (353 K, 98% RH), respectively. This is the first time that guest molecules were introduced into HOFs. The stability and proton conductivity of the HOFs are improved due to the interaction of imidazole with carboxyl groups and water molecules.
