“…After 10 s of UV irradiation at a low intensity of 0.5 mw/cm 2 , a clear color change from yellow to cyan blue was observed. A response was observed with a UV irradiance intensity as low as 0.1 μW/cm 2 (Figure S24), which is comparable to commercialized UV light radiation devices, lower than that reported for ultraviolet light detection materials. ,,− The color-saturated samples of Zn-MOFs-1–5 were completely decolored after being kept in the dark for 9, 28, 41, 25, and 47 h at room temperature, respectively (Figure S25). This reversible color conversion could be repeated three times without a significant color loss.…”

“…Upon UV light irradiation, the UV–vis spectra showed new strong bands centered at 627–751 nm (Figures S43–S47), while the ESR spectra showed stronger and symmetric single-peak radical signals, confirming the existence of photogenerated radicals (Figures S48–S52). − ,, For Zn-MOFs-1, 3, and 4, the shortest distances between the O of carboxylate groups and the N of the pyridinium unit were 3.48, 3.83, and 3.56 Å, respectively, satisfying the photoinduced electron paths. The shorter distances are more favorable for electron transfer.…”

The encapsulation of various guest molecules into the pores of metal−organic frameworks (MOFs) to form hybrid materials has attracted significant attention due to their unique spatial distribution and certain preferential geometry of the guests inside the MOFs. This arrangement often results in the guests exhibiting unique physical and chemical properties due to their intramolecular interactions with the host. In this article, five viologen derivatives were introduced as guests in a Zn-MOF with different benzene ring lengths, resulting in the formation of host−guest three-dimensional (3D) MOFs. The five compounds exhibited guest-dependent emission wavelength, color, and excellent photochromic behavior upon ultraviolet (UV) light radiation due to the distinct electronic transfer and π•••π stacking interactions between the viologen guests and the host framework. This study provides a host−guest strategy for designing color-tunable luminescent and highly sensitive photochromic materials.

“…Efficient fluorophores such as coumarin and naphthylimide have also been utilized. 23 Therefore, Li's team synthesized novel caging dyes NPE-HCCC2/AM 15 c and CCC-1 4 b based on coumarin. These dyes exhibit a fairly high quantum yield ( Q = 6000 M −1 cm −1 ) and emit bright blue and green fluorescence upon 365 nm photoactivation.…”

“…Chen et al developed the novel photocage 8 containing glycine-linked naphthalimide and o-nitrobenzyl groups (Figure 5). [19] Upon irradiation, 8 releases a fluorescent naphthalimide derivative through different routes shown in Figure 5. The released fluorescence intensity is linearly correlated with the intensity of UV irradiation.…”

Photocages are a class of substances containing photosensitive groups, also known as "photoremovable protecting groups", from which target substances are released upon exposure to specific wavelengths of light. The substances released in the light-promoted processes have chemical or biological properties that enable them to carry specifically designed functions. As a result, photocages can be utilized in various fields such as chemistry, biology, and medicine. In this paper, progress made in research carried out in recent years aimed at developing photocage molecules with different photosensitive moieties is reviewed. K E Y W O R D Sphoto-controlled release, photocage, photoprotecting group, photoremoveable protecting group Yajing Li and Maolin Wang contributed equally to this study.
