摘要

Polyoxometalate-based metal–organic framework (POM-MOF) hybrid materials have received increasing attention, and have the advantages of both POMs and MOFs. Herein, we encapsulate lanthanide(III) (Ln3+) cations (Eu3+, Tb3+, Sm3+ and Dy3+) in the channels of [Cu2(BTC)4/3(H2O)2]6[HPMo12O40]·(C4H12N)2·xH2O (x = 25–30, NENU-5) nanocrystals by exchanging the (C4H12N)+ with Ln3+. The structure, composition, thermal stability, morphology, and absorption of ultraviolet and visible light of the obtained hybrids are characterized by PXRD, ICP, FTIR, SEM and UV-vis DRS. The photophysical properties of these materials are investigated in detail under ultraviolet radiation, displaying the characteristic emission line of the corresponding Ln3+ ions. These physical characterizations prove that these hybrid materials exhibit a uniform mesoporous structure, good crystallization and multi-color luminescence. Furthermore, photofunctional Ln3+ functionalized POM-MOF hybrids are dispersed in an ionic liquid compound (1-(2-hydroxyethyl)-3-methylimidazolium bromide) which has little effect on luminescence to produce a soft ion gel. Finally, we manufacture their thin films by assembling the hybrids on a quartz plate using a polymer linker to achieve further practical application. Both the fluorescence of lanthanide hybrid materials and that of thin films can be adjusted by different Ln3+ compositions or excitation wavelengths and finally reach white light output.
