“…Although some effective strategies have been reported to achieve novel luminescence in metal-organic frameworks, [53][54][55][56][57] customizing luminescence in crystalline clusterassembled materials (CAMs) still presents a challenge. Favorably, the ultralarge pore diameter of 1 endows it with a potential to encapsulate some large functionalized guest molecules beside small solvent molecules, hence providing the possibility for tailoring its luminescence.…”

Crystalline cluster-assembled materials (CAMs) are emerging as types of exploratory fabrications due to their atomically precise structures and intriguing chemical/physical properties, as well as their luminescent function. However, constructing novel luminescent porous crystalline CAMs present an enduring and significant challenge owing to their instability and poor ambient-temperature photoluminescent quantum yields. In this work, we synthesized successfully, a mesoporous crystalline CAM (1 ⊃ DMAC), based on silver-chalcogenolate cluster and 1,1,2,2-tetrakis(4-(pyridin-4-yl)phenyl)ethene (TPPE) ligand, with highsymmetry structure and ultralarge pores. 1 ⊃ DMAC exhibited adjustable intense luminescence, originating from aggregation-induced emission (AIE) properties of the TPPE ligand. The diameter of the cubic cage in 1 ⊃ DMAC was as high as 32 Å, which endowed it with satisfactory encapsulation capacity for different guest molecules. Interestingly, by adjusting functionalized guest molecules, circularly polarized luminescence, white-light-emitting, and room-temperature phosphorescence were readily realized. 1 ⊃ DMAC could enrich limited kinds of mesoporous crystalline CAMs and offers the prospect of application in host-guest chemistry. More importantly, this work provides a strategy, versatile for tailoring luminescence in crystalline porous materials.

“…In our constructed nanoplatform (MH-PLGA-IR780 NPs), cancer cell membrane-coated NPs had the advantages of high spatial resolution and deep penetration [ 32 ]. In addition, with the development of light sources, deep PDT uses two-photon excitation [ 52 ], X-ray [ 53 ], or NIR-II [ 54 ] as light sources to provide better penetration ability to treat tumors lying under deep tissues [ 55 ]. We will try to construct multifunctional NPs with deeper PDT penetration in future research.…”

Background No prominent advancements in osteosarcoma (OS) treatment have been made in the past 20 years. Although photodynamic therapy (PDT) is an emerging technique for cancer therapy, the lack of targeted photosensitizers for OS treatment severely limits its applications. Results In this study, we constructed a potential theranostic nanoplatform by using (poly (lactic-co-glycolic) acid (PLGA) nanoparticles (NPs) encapsulating IR780 into the shell (PLGA-IR780 NPs), which were further camouflaged with human OS cell membranes from the HOS cell line (MH-PLGA-IR780 NPs). These constructed NPs showed the capacity for homologous targeting with excellent photoacoustic (PA)/fluorescence (FL) imaging ability. Benefitting from their homologous targeting capacity, MH-PLGA-IR780 NPs obviously promoted cell endocytosis in vitro and tumor accumulation in vivo, which could further improve PDT performance under near-infrared (NIR) irradiation. In addition, to their homologous targeting and PA/FL dual-mode imaging ability, MH-PLGA-IR780 NPs had advantages in penetrating deeper into tumor tissues and in real-time dynamic distribution monitoring in vivo, which laid a foundation for further clinical applications in OS. Moreover, we demonstrated that PDT guided by the constructed NPs could significantly induce HOS cells apoptosis and ferroptosis via excessive accumulation of reactive oxygen species (ROS), and further determined that the potential anticancer molecular mechanism of apoptosis was triggered by the release of cytochrome c-activated mitochondrial apoptosis (endogenous apoptosis), and that ferroptosis caused the activation of nuclear receptor coactivator 4 (NCOA4)-mediated ferritinophagy and the inactivation of glutathione peroxidase 4 (GPX4), synergistically leading to excessive accumulation of Lipid-ROS and Lipid peroxides (LPOs). Concurrently, MH-PLGA-IR780 NPs-guided PDT also showed an obvious inhibitory effect on tumor growth in vivo. Conclusion These results suggest that this homologous targeting-based theranostic nanoplatform provides an effective method to improve PDT performance in OS and contributes a new and promising approach for OS therapy.

“…Organic fluorescent dyes as an important type of luminescent materials have held great potential for fluorescent labeling, bioimaging, environmental determination, and other optoelectronic applications because of their merits of high quantum yields, broad emission widths, large absorption coefficients, and facile chemical tunability. − However, most of them suffer from strong aggregation-caused quenching (ACQ) effects in the solid-state, which are unsuitable for direct use as solid lighting materials. , To suppress the ACQ effects that will reduce the emission intensity, the dispersion of dye molecules into a porous matrix is desirable. , In this regard, metal–organic frameworks (MOFs) can serve as a promising porosity matrix for the encapsulation of dye molecules. The tunable porosity and highly designable framework of MOFs make them a promising platform to load the dyes and pre-install functional sites for enhancing the interactions between the framework and dye molecules. − Also, MOFs with appropriate emission can serve as a promising platform to sensitize the luminescence of the dye through fluorescence resonance energy transfer (FETR). − With these advantages, many dye-encapsulated MOFs have been reported and have been applied in white light materials. − However, the investigation on white-light-emitting MOF@dye composites is still in its relative infancy and has some tough issues: (1) the stability of most MOF hosts is relatively poor, thereby restricting their application scope; (2) weak interactions between the MOF and encapsulated dyes may result in the poor stability of the MOF@dye composites due to the leaking of dyes; and (3) the quantum yields (QYs) of reported white-light-emitting MOF@dye composites are still relatively low, that make them insufficient for practical applications. This motivates the pursuit of novel MOF-based white-light emission materials with good color quality and high QY.…”

Owing to their rich porosity and structural diversity, metal–organic frameworks (MOFs) offer substantial advantages over other emission sources for the precise design and color regulation of white-light phosphors. However, achieving efficient white-light emission remains a considerable challenge. Herein, we report a strategy to achieve tunable and efficient white-light emission by regulating energy transfer in a multicomponent dye-loaded MOF. An anionic MOF NKU-114 featuring appropriate confined spaces is designed as a host to deliberately encapsulate three red-, green-, and blue-emissive dyes with adaptive spectral overlap, DSM, AF, and 9-AA, respectively, yielding the NKU-114@dyes composites. Integrating the suitable spectral overlap and efficient energy transfer between the dyes and the framework produced a white-light emission material containing the multicomponent dyes NKU-114@DSM/AF/9-AA. The obtained material has a broadband white emission with a high quantum yield (up to 42.07%) and nearly identical CIE coordinates of (0.34, 0.32), and the moderate correlated color temperature and color-rendering index value can reach up to 5101 K and 81, respectively, suggesting the potential of the multicomponent dye-loaded MOF for white-light-emitting phosphors with good color quality.
