The invention discloses preparation and application of a high-stability fluorescent sensing material. A nail complex is designed and synthesized, so that the number of polymerizable functional groups in the composite xerogel is reduced, the rigidity and polarity of a matrix are reduced, and the optical sensing performance of the material is improved to a certain extent; (2) mesoporous silica with a core-shell structure is designed and synthesized, and then a fluorescent indicator derivative is covalently grafted into mesopores in the surface of SiO2 (at) mSiO2, so that the material has extremely high stability; (3) the fluorescent sensing material designed by the invention is good in compatibility, and can be applied to various detections such as pH detection, oxygen content detection, nitrogen-containing compound detection, heavy metal ion detection, organic pollutant detection and the like. 本发明公开了一种高稳定性荧光传感材料的制备及应用；属于荧光传感技术领域：(1)本发明设计合成了钉配合物，使得复合干凝胶中可聚合的功能团数目减少，降低了基质的刚性和极性，一定程度上提高了材料的光学传感性能；(2)本发明设计合成了核壳结构介
