Selective probing of one molecule from one class of similar molecules is highly challenging due to their similar chemical and physical properties. Herein, a novel metal–organic framework FJI‐H15 with flexible porous cages has been designed and synthesized, which can specifically recognize ethylbenzene with ultrahigh enhancement efficiency from a series of alkyl‐aromatics, in which an unusual size‐dependent interaction has been found and proved. It can also selectively detect phenolic‐nitroaromatics among a series of nitroaromatics based on energy transfer and electrostatic interactions. Such unusual specificity and variable mechanisms responding to different types of molecules have not yet been reported, which will provide a new strategy for the development of more effective chemosensors based on MOFs for probing small structural differences in molecules.

多孔框架作为可变化学传感器：从特定的致癌烷基芳烃到爆炸性硝基芳香烃的选择性检测的响应。

由于它们的相似的化学和物理性质，从一类相似的分子中选择性探测一个分子具有很高的挑战性。在这里，一种新颖的金属有机框架FJI - H15设计并合成了具有柔性多孔笼的复合物，它可以通过一系列烷基芳族化合物特异性识别超高增强效率的乙苯，其中发现并证明了一种不寻常的尺寸依赖性相互作用。它也可以基于能量转移和静电相互作用，选择性地检测一系列硝基芳族化合物中的酚-硝基芳族化合物。尚未报道这种响应不同类型分子的异常特异性和可变机制，这将为开发更有效的基于MOF的化学传感器以探测分子中的微小结构差异提供新的策略。
