Artificial Light‐Harvesting Pt(II) Amine Cage and Its Application as Security Ink
A new platinum (II)-triphenylamine tetra aldehyde-based barrel-shaped rectangular covalent cage was prepared using dynamic imine condensation and subsequent reduction. The cage was found to exhibit aggregation-induced emission behavior in 60% water in THF solvent composition and the AIE property was successively utilized to achieve excellent sequential light-harvesting behavior in aggregate form in the presence of acceptors such as Eosin Y and Nile Red. Moreover, the light-harvesting capability was employed to prepare a new type of security ink whose potential was demonstrated using TLC plates and commercial banknotes.
