发光基团自组装成多孔金属有机框架（mof）产生了许多探测挥发性有机分子（VOMs）的发光平台。然而，迄今为止所探索的大多数都是基于一个跃迁的发光强度，这对于探测不同的VOMs是不有效的。我们合成了一种含有一维纳米管通道的发光MOF材料，并进一步开发了一个发光dye@MOF平台，通过调节两种不同发射之间的能量转移效率来实现对不同vom的探测。dye@MOF平台显示VOM与配体与染料基团的发射峰高比之间具有良好的指纹相关性。dye@MOF传感器具有自校准、稳定和瞬时性，因此该方法应该是一种非常有前途的策略，可以开发具有前所未有实际应用的发光材料。
Self-assembly of luminescent moieties into porous metal-organic frameworks (MOFs) has generated many luminescent platforms for probing volatile organic molecules (VOMs). However, most of those explored thus far have only been based on the luminescence intensity of one transition, which is not efficient for probing different VOMs. We have synthesized a luminescent MOF material containing 1D nanotube channels, and further developed a luminescent dye@MOF platform to realize the probing of different VOMs by tuning the energy transfer efficiency between two different emissions. The dye@MOF platform exhibits excellent fingerprint correlation between the VOM and the emission peak-height ratio of ligand to dye moieties. The dye@MOF sensor is self-calibrating, stable, and instantaneous, thus the approach should be a very promising strategy to develop luminescent materials with unprecedented practical applications.
