Herein, we report on a new strategy for fabricating a luminescent monolayer thin film by modified metal-organic frameworks (MOFs). Lanthanide ion (Eu3+, Tb3+ and Yb3+) is first introduced to MOFs (MOF-253), and then the second ligand, i.e. TTA or TAA (TTA = 2-thenoyltrifluoroacetone and TAA = 1,1,1-trifluoropentane-2,4-dione), is used to further sensitize the lanthanide ion. Finally, the MOFs modified by the lanthanide complex are assembled on a quartz plate by a functional linker. The as-prepared MOF thin film is a dense and transparent monolayer, and its thickness is less than 100 nm. Four kinds of optically functionalized MOF thin film are prepared by this method.
