Herein, we developed a hybrid material, denoted as SiQDs@ZIF-8@Eu3+@HPU-14, serving multifunctional platform for different analytes. In this probe, selected SiQDs encapsulated in ZIF-8 the responsive fluorescent fragment salicylaldehyde (SA) yielding turn-on signal, which was attributed to reaction between -NH2 and aldehyde group of SA via C=N binding Schiff base linkage. Simultaneously, Eu3+ functionalized HPU-14 employed turn-off switch SA, resulted by competitive absorption reduced ligand-metal energy transfer effect. The two signals enable SiQDs@ZIF-8@Eu3+@HPU-14 show specific recognition with low detection limit 138 nM. Notably, after sensing also exhibited target-specific Al3+ Pb2+ through modes. Specifically, emissions were enhanced Al3+, whereas at 618 nm remained unchanged. presence Pb2+, both perturbed. limits are 321 165 nM, respectively. Furthermore, mixed substrate film logical gate systems designed, offering prospects intelligent portable sensing.

Bimetallic metal–organic frameworks (MOFs) capable of sensing external stimuli will provide more possibilities for further regulating third-order nonlinear optical (NLO) properties. In this work, we synthesized bimetallic MOFs (ZnCu-MOF and ZnCd-MOF) through central metal exchange using a photoresponsive Zn-MOF as precursor. Compared with Zn-MOF, both ZnCu-MOF ZnCd-MOF exhibit significantly enhanced NLO absorption This is mainly attributed to the introduction ions different electron configurations that can adjust bandgap enhance delocalization, thus promoting transfer. Interestingly, show transition from reverse saturation (RSA) (SA) after exposure ultraviolet irradiation, they retain properties directional photogenerated Photoresponsive not only have effect modulation electronic structures but also characteristics photoinduced transfer, exhibiting diversified These findings novel method development multifunctional materials.

Defect engineering plays a pivotal role in regulating electronic structure and facilitating charge transfer, yielding captivating effects on third-order nonlinear optical (NLO) properties. In this work, we utilized mixed-linker strategy to intentionally disrupt the initial periodic arrangement of UiO-66 construct defects. Specifically, incorporated tetrakis(4-carboxyphenyl)porphyrin (TCPP) with an exceptionally electron-rich delocalization system into framework using one-pot solvothermal method, ingeniously occupying partial distribution sites Zr6 clusters. Compared UiO-66, NLO absorption refraction performance TCPP/UiO-66 were significantly improved. Additionally, due presence nitrogen-rich that can accommodate metal ions porphyrin ring TCPP, Co(II), Ni(II), Cu(II), Zn(II) are introduced TCPP/UiO-66, extending d–π conjugation effect further regulate The behavior transforms saturation (SA) reverse (RSA), while shifts from self-defocusing self-focusing. This work shows defects effectively structure, TCPP crucial enhancing electron delocalization.

MOF@CeO2 composites with good interfacial compatibility have garnered significant attention in the field of third-order nonlinear optics (NLO). However, interaction between MOFs and CeO2 is commonly weak, which severely weakens NLO properties composites. In this study, we chose parent Zn-MOF ({[Zn(BPAN)0.5(ndcpa)]·DMA·H2O}n) (BPAN = 9,10-bis(4-pyridyl)anthracene H2ndcpa naphthalene-2,6-dicarboxylicacid) synthesized bimetallic-MOFs (ZnNi-MOF ZnCo-MOF) by solvent-assisted metal-ion exchange. The defect sites originating from exchange make interface bimetallic-MOF@CeO2 (ZnNi-MOF@CeO2 ZnCo-MOF@CeO2) stronger. results indicate display enhanced reverse saturable absorption self-defocusing refraction compared to Zn-MOF@CeO2, can be attributed efficient charge transfer at interfaces. Transient spectra theoretical calculation revealed that significantly reduced energy loss, electron efficiency, positively modulated properties.
