Abstract:
The luminescent MOF [(CH 3 ) 2 NH 2 ] 2 [(Zn 2 O)L]⋅5 DMF (NENU‐519, NENU=Northeast Normal University) with a zeolite BCT topology was successfully synthesized. It is a rare example of a two‐fold interpenetrated framework with a zeolite topology. NENU‐519 demonstrates the ability to selectively adsorb cationic dyes. Furthermore we developed Rh6@NENU‐519 (Rh6=Rhodamine 6G) as a dual‐emitting sensor for probing different volatile organic molecules (VOMs) due to an energy transfer between L and the dye. The composite can be used to distinguish the isomers of o‐ , m‐ , and p‐ xylene and ethylbenzene using the emission‐peak‐height ratios of L to the dye as detectable signals, in which the readout signals are involved in the interactions between the dye@MOF composite and the guest analytes. Moreover, Rh6@NENU‐519 can serve as a luminescent switch for the detection of different aromatic compounds, like benzene, benzene substituted with different groups, and pyridine. In other words, the Rh6@NENU‐519 composite can be used as molecular decoder of the structural information of different VOMs into recognizable luminescent signals. Hopefully this work will open a new corridor to develop luminescent guest@MOF composites as sensors for practical applications.
