Pyridine zinc complex as well as preparation method and application thereof

The invention belongs to the technical field of luminescent materials, and particularly relates to a pyridine zinc complex as well as a preparation method and application thereof. The invention provides a pyridine zinc complex which has a structure as shown in a formula I. The pyridine zinc complex provided by the invention can emit green afterglow after being excited by an ultraviolet lamp with the wavelength of 365 nm and emit orange afterglow after being excited by an ultraviolet lamp with the wavelength of 395 nm, so that green and orange double-color long afterglow luminescence is realized. 本发明属于发光材料技术领域，具体涉及一种吡啶锌配合物及其制备方法和应用。本发明提供了一种吡啶锌配合物，具有式Ⅰ所示结构。本发明提供的吡啶锌配合物能够在波长为365nm的紫外灯激发后发出绿色余辉，在波长为395nm的紫外灯激发后发出橙色余辉，实现了绿色和橙色双色系的长余辉发光。
