“…Third, the H 4 TCPE molecule had a relatively large structure, coupled with its rich coordination sites, making it an ideal material for constructing stable porous structures, which could not only accommodate the analyte and increase the contact area to increase detection sensitivity and speed 38 but also accommodate special guest molecules such as (H 2 O) to enhance the proton conductivity of the material. 39 Finally, H 4 TCPE had a completely rigid structure, and Bi 3+ had high affinity for O. The MOFs constructed in this work had high stability and could meet the material's application requirements under severe conditions.…”

Metal organic frameworks (MOFs) constructed with bismuth metal have not been widely reported, especially multifunctional Bi-MOFs. Therefore, developing multifunctional MOFs is of great significance due to the increasing requirements of materials. In this work, a 3D Bi-MOF (Bi-TCPE) with multifunctionality was successfully constructed, demonstrating high thermal stability, water stability, a porous structure, and strong blue fluorescence emission. We evaluated the properties of Bi-TCPE in detecting anions (S 2− , Cr 2 O 7 2− , and CrO 4 2− ) in aqueous solution, along with the rapid visual detection of H 2 S gas and proton conduction. In terms of anion detection, Bi-TCPE achieved the rapid detection of trace S 2− in aqueous solutions, while the K sv value was 1.224 × 10 4 M −1 with a limit of detection (LOD) value of 1.93 μM through titration experiments. Furthermore, Bi-TCPE could sensitively detect Cr 2 O 7 2− and CrO 4 2− , with K sv values of 1.144 × 10 4 and 1.066 × 10 4 M −1 , respectively, while LOD reached 2.07 and 2.18 μM. Subsequently, we conducted H 2 S gas detection experiments, and the results indicated that Bi-TCPE could selectively detect H 2 S gas at extremely low concentrations (2.08 ppm) and with a fast response time (<10 s). We also observed significant color changes under both UV light and sunlight. Therefore, we developed a H 2 S detection test paper for the rapid visual detection of H 2 S gas. Finally, we evaluated the proton conductivity of Bi-TCPE, and the experimental results showed that the proton conductivity of Bi-TCPE reached 4.77 × 10 −2 S•cm −1 at 98% RH and 90 °C, achieving an excellent value for unmodified and encapsulated MOFs. In addition, Bi-TCPE showed high stability in proton conduction experiments (it remained stable after 21 consecutive days of testing and 12 cycles of testing), demonstrating relatively high application value. These results indicate that Bi-TCPE is a multifunctional MOF material with great application potential.
