Metal−organic frameworks (MOFs) represent a versatile class of porous reticular materials whose structures and properties can be precisely tailored for targeted applications. A prominent example of such an application is the chemiresistive sensing of gases, where MOFs exhibit robust responses even at room temperature, thereby demonstrating their potential for practical utilization. This feature article reviews the development of the design criteria that are crucial for the optimization of MOFs as room-temperature chemiresistors. To highlight key advancements in this field, we categorize these materials into three distinct groups to (1) 2D conductive MOFs, (2) composites of MOFs with other materials, and (3) MOF-on-MOF architectures. The representative achievements from each group are discussed to demonstrate research progress in the construction of these innovative materials and their performance in gas sensing. Special emphasis is placed on the MOF-on-MOF materials, underscoring their role as pioneering smart materials for targeted application.

“…The unique characteristics of MOFs, distinguished by their ultrahigh surface area, tunable structures, diverse chemical functionality, and varied optical properties, position them as frontrunners in nanomaterial research. These crystalline networks, comprising metal ions coordinated with organic ligands, offer versatility that allows researchers to customize MOFs for numerous applications, such as gas storage, separation, catalysis, and sensing. − They are particularly promising for photodetection applications due to their high surface area and amenability to modification. The inclusion of MOFs in photodetector designs can enhance the spectral selectivity and sensitivity.…”

An innovative strategy is introduced, integrating metal−organic frameworks (MOFs) and bare carbon nanofibers (CNFs) within a nanocomposite, to address the challenges related to the broad absorption spectrum of traditional photodetectors. This advancement aims to eliminate the need for additional filters or intricate surface patterning in traditional photodetectors to achieve spectral selectivity, which is associated with high costs, and to facilitate enhanced spectral selectivity in the visible range, thereby paving the way for their widespread commercial adoption. By strategically leveraging the inherent strengths of both MOFs and CNFs while addressing their individual limitations, our method not only resolves challenges related to 3D MOFs and CNFs in spectrally selective photodetection but also significantly enhances optoelectronic properties. The resulting nanocomposite exhibits spectrally selective detection of violet light in the visible range, achieving a significantly enhanced responsivity of 27 A/W, detectivity of 1.66 × 10 11 Jones, and high external quantum efficiency of 8215% at a low optical power intensity of 27 μW/cm 2 at room temperature. This approach holds significant promise to advance photodetection technology in various applications requiring high-performance and spectrally selective detectors.
