Metal-organic frameworks (MOFs) provide broad prospects for the development of various types of luminescence sensors due to their versatile structures and tunable luminescence characteristics. In order to overcome the main drawbacks of singleemission luminescence sensors, such as being susceptible to the fluctuation of probe concentration and interference from external conditions, the ratiometric luminescent sensors utilizing the ratio between the intensity of two emssions within the same luminescent material, have been widely developed in recent years. We are committed to designing and developing luminescent ratiometric MOF-based sensors toward a wide range of targeted functional species. In this mini-review article, after the general description of ratiometric luminescent sensors, we have summarized our recent advances in the strategies for synthesizing dual-emitting MOFs and their applications for ratiometric sensing of temperature, pH, biomarkers and water, as well as the related sensing mechanisms.

“…It is often encountered as a part of reticular syntheses due to its predictable geometry and availability. Its relatively large conjugated electron system, as well as a certain degree of flexibility make it interesting for the synthesis of luminescent MOFs [72,73]. "Rigidifying" of the ligand conformation in the resultant MOF often leads to the enhancement of stilbene-based luminescence, which allows the preparation of highly emissive and stable materials [74].…”

Coordination Polymers Based on Highly Emissive Ligands: Synthesis and Functional Properties

Coordination polymers are constructed from metal ions and bridging ligands, linking them into solid-state structures extending in one (1D), two (2D) or three dimensions (3D). Two- and three-dimensional coordination polymers with potential voids are often referred to as metal-organic frameworks (MOFs) or porous coordination polymers. Luminescence is an important property of coordination polymers, often playing a key role in their applications. Photophysical properties of the coordination polymers can be associated with intraligand, metal-centered, guest-centered, metal-to-ligand and ligand-to-metal electron transitions. In recent years, a rapid growth of publications devoted to luminescent or fluorescent coordination polymers can be observed. In this review the use of fluorescent ligands, namely, 4,4′-stilbenedicarboxylic acid, 1,3,4-oxadiazole, thiazole, 2,1,3-benzothiadiazole, terpyridine and carbazole derivatives, naphthalene diimides, 4,4′,4′′-nitrilotribenzoic acid, ruthenium(II) and iridium(III) complexes, boron-dipyrromethene (BODIPY) derivatives, porphyrins, for the construction of coordination polymers are surveyed. Applications of such coordination polymers based on their photophysical properties will be discussed. The review covers the literature published before April 2020.

“…The matched pore size between the guest and MOF can avoid the leakage of guests. [30][31][32][33] Accordingly, the choice of ligand is crucial in the synthesis of MOFs with specific functions. For example, Qiu et al synthesized [Zn 2 (tipe) 1.5 (AIP)](NO 3 ) 2 •7DMA•7H 2 O using the 1,1,2,2-tetrakis(4-(imidazol-1-yl)phenyl)ethane (tipe) ligand and 5-aminoisophthalic acid (H 2 AIP) ligand and realized white light emission by encapsulating dye molecules.…”
