“…Thus, there is a gradual increase in the degree of intramolecular vibration restriction, which in turn favors more blue emission. The slight decrease of the fluorescence intensity when the water content is above 70% might be caused by excessive aggregation of fluorescent molecules into amorphous aggregates . A CIE coordinate diagram (Figure c) indicates that the fluorescence of these mixtures have passed through the white-light region [CIE (0.3265, 0.3266), f w = 44%].…”

“…The slight decrease of the fluorescence intensity when the water content is above 70% might be caused by excessive aggregation of fluorescent molecules into amorphous aggregates. 39 A CIE coordinate diagram (Figure 1c) indicates that the fluorescence of these mixtures have passed through the white-light region [CIE (0.3265, 0.3266), f w = 44%]. The fluorescence photographs in Figure 1d also clearly show that the fluorescence color changed from orange (Φ = 4.92%) to white (Φ = 3.77%) and then blue (Φ = 8.50%) as the water fraction was increased; the corresponding fluorescence lifetimes are listed in Table S1 in the Supporting Information.…”

White-light-emitting materials have attracted wide interest for potential applications in information displays and lighting. To date, the majority of reported white-light-emitting materials have been multicomponent systems that are typically processed with organic solvents. These features are associated with complex processing, poor white-light quality, and environmental pollution. Herein, a white-light-emitting aqueous system is realized by encapsulating a fluorophore, which has a vibration-induced emission effect, in Pluronic F127 micelles. Tunable multicolor fluorescence is achieved by changing the temperature, and the use of organic solvents is effectively avoided. Through this process, white-light emission with Commission Internationale de l’Eclairage coordinates of (0.3351, 0.3326) is obtained, which is very close to pure white light, and its color rendering index is as high as 89. The fluorescence color tunability of this system could be performed in a wide temperature range, rendering it a potential material in optical thermometry. Besides, the aqueous system also allows for the application of the material as a fluorescent ink and white-light-emitting hydrogels. Information could be embedded in paper-based materials and hydrogels through the fluorescence quenching effect of iron ions (Fe3+) on the fluorophore. Fluorescence could then be recovered upon removal of Fe3+ by adenosine 5′-triphosphate. Thus, fluorescent patterning and triple-mode anti-counterfeiting could be expected due to the temperature-sensitive emission, fluorescence quenching, and recovering properties.

“…Base-promoted nucleophilic aromatic substitution reactions of electron-deficient fluoroarenes with amines have been proven to be one of the most efficient reactions to form C–N bonds . In 2019, we successfully prepared 9,14-diphenyl-9,14-dihydrodibenzo[ a , c ]phenazines via the nucleophilic aromatic substitution reactions of phenanthrene-9,10-diamines with 1,2-difluoro-4-nitrobenzene in a good yield (Figure d) . However, this synthetic approach is limited to reactants of difluorobenzenes with electron-deficient groups such as nitro and cyano groups.…”

Organic fluorophores with dynamic conformations in the excited state have played a significant role in applications of organic functional dyes. Among them, dihydrophenazine-based dynamic fluorophores involving a photoinduced structural planarization process in the excited state exhibited large Stokes shifts and conformation-dependent multicolor emissions. With the developments of synthetic strategies, precise modifications on dihydrophenazinebased scaffolds have successfully afforded a variety of precise molecular structures of varying sizes and compositions, which have delicately modulated their photophysical properties. Herein, this Perspective summarizes the precise modulations of dihydrophenazine-based dynamic fluorophores, including the development of the synthetic methodologies, and tailor-made molecular models to reveal the luminescence−structure relationships. Insights about the future molecular design and applications are also presented.

“…based on various mechanisms, such as deprotection, [10][11][12][13] coordination, 14,15 Michael additions, [16][17][18][19][20] and reaction with aldehyde [21][22][23][24][25][26][27][28][29][30][31][32][33] because of their high sensitivity, short response time, good selectivity, and simple operation. However, most probes are constructed from classic dyes such as coumarin, 34,35 BODIPY, 36 and cyanine.…”
