Multicolor adjustable dynamic long-life room-temperature phosphorescent mono-pyridinium salt-based ionic polymer as well as preparation method and application thereof

The invention belongs to the field of multifunctional optical materials, and particularly relates to a multicolor adjustable dynamic long-life room-temperature phosphorescent mono-pyridinium salt-based ionic polymer as well as a preparation method and application thereof. Polyvinyl alcohol is doped with a single pyridinium salt ion functional monomer or polyvinyl alcohol is co-doped with the single pyridinium salt ion functional monomer and a second phosphorescent luminous monomer to prepare the room-temperature phosphorescent ionic polymer with photochromism, excitation wavelength dependence and long service life. The obtained multi-color adjustable dynamic long-life room temperature phosphorescence mono-pyridinium salt-based ionic polymer has multiple dynamic characteristics of fluorescence, long-life room temperature phosphorescence, adjustable phosphorescence life, photochromism, excitation wavelength dependence, adjustable luminescence color and the like, and has important application potentials in the f
