Abstract:
A near-infrared (NIR) emissive artificial light-harvesting system with two-step high-efficiency sequential resonance energy transfers was fabricated based on the in situ growth of MAPbBr3 quantum dots in the supramolecular self-assembly of a Zn(II) carboxyl-functionalized pillar[5]arene coordination polymer and two different fluorescent dyes, eosin Y and Nile blue. This system could realize NIR fluorescent imaging of the sweat pores of latent fingerprints, opening a new avenue to design perovskite-based NIR emitting artificial light-harvesting systems for third-level fingerprint imaging.
