“…Therefore, it is of great significance and urgency to explore a new chemical-sensing method to detect and sense metal ions and other detection substances with the naked eye. The fluorescence analysis method [24][25][26][27] is called "nondestructive testing" due to its nondestructive, highly sensitive, highly selective and rapid detection characteristics, which has attracted considerable attention in the field of testing and is a relatively popular testing method [28].…”

In this study, a red-green dual-emitting fluorescent composite (RhB@MOFs) was constructed by introducing the red-emitting organic fluorescent dye rhodamine B (RhB) into metal-organic frameworks (Tb-MOFs). The sample can be used as a ratiometric fluorescent probe, which not only avoids errors caused by instrument and environmental instability but also has multiple applications in detection. The results indicated that the RhB@MOFs exhibited a turned-off response toward Fe3+ and a turned-on response for the continuous detection of ascorbic acid (AA). This ratiometric fluorescent probe possessed high sensitivity and excellent selectivity in the continuous determination of Fe3+ and AA. It is worth mentioning that remarkable fluorescence change could be clearly observed by the naked eye under a UV lamp, which is more convenient in applications. In addition, the mechanisms of Fe3+- and AA-induced fluorescence quench and recovery are discussed in detail. This ratiometric probe displayed outstanding recognition of heavy metal ions and biomolecules, providing potential applications for water quality monitoring and biomolecule determination.

“…Numerous examples have recently been reviewed for polarity sensitive probes of various subcellular structures [ 13 , 14 , 15 , 16 ], reactive oxygen and nitrogen species [ 17 , 18 ], viscosity sensitive probes based on the rotor effect [ 19 , 20 , 21 ] and AIE-effect [ 22 , 23 , 24 ], polarity-controlled triplet photosensitizers for photodynamic therapy [ 25 , 26 , 27 ], photoswitches, and photocages for theranostic applications [ 28 , 29 , 30 , 31 , 32 ], among others. In some cases, the insensitivity of BODIPY sensors to solvent polarity makes them ideal for bioimaging [ 15 , 33 , 34 ].…”

This research work is devoted to collecting a high-quality dataset of BODIPYs in a series of 10–30 solvents. In total, 115 individual compounds in 71 solvents are represented by 1698 arrays of the spectral and photophysical properties of the fluorophore. Each dye for a series of solvents is characterized by a calculated value of solvatochromic sensitivity according to a semiempirical approach applied to a series of solvents. The whole dataset is classified into 6 and 24 clusters of solvatochromic sensitivity, from high negative to high positive solvatochromism. The results of the analysis are visualized by the polarity mapping plots depicting, in terms of wavenumbers, the absorption versus emission, stokes shift versus − (absorption maxima + emission maxima), and quantum yield versus stokes shift. An analysis of the clusters combining several dyes in an individual series of solvents shows that dyes of a high solvatochromic sensitivity demonstrate regular behaviour of the corresponding plots suitable for polarity and viscosity mapping. The fluorophores collected in this study represent a high quality dataset of pattern dyes for analytical and bioanalytical applications. The developed tools could be applied for the analysis of the applicability domain of the fluorescent sensors.
