CuIP2S type complex and composite device and fluorescence sensing application thereof

The invention discloses a CuIP2S type complex luminescent material, a preparation method of the CuIP2S type complex luminescent material, and sensing application of the CuIP2S type complex luminescent material to pyridine VOC (Volatile Organic Compounds). The structural formula of the luminescent material is CuI (p-Tol3P) 2 (DMMP), in the formula, p-Tol3P is an electrically neutral monophosphine ligand tris (p-methylphenyl) phosphine, and DMMP is a sulfur-containing ligand 4, 6-dimethyl-2-mercaptopyrimidine; the complex is prepared by sequentially carrying out coordination reaction on CuI and a ligand, and also can be prepared by ball milling; the material emits red light and can be used as a luminescent material; after the material is placed in a pyridine or p-methylpyridine atmosphere, fluorescence enhanced sensing response is quickly presented; the material is easy to prepare and has good solubility and stability, a paper-based or polymer-doped sensing film is also easy to prepare, and the film also quickl
