Circularly Polarized Room-Temperature Phosphorescence from Marine Polysaccharide-Based Helical Assemblies
Development of circularly polarized room-temperature phosphorescence (CP-RTP) materials based on natural macromolecules remains a great challenge. Herein, we demonstrate a chiral coassembly approach to construct CP-RTP materials using marine polysaccharides. The chiral anionic λ-carrageenan (λ-Car) coassembles with the achiral cationic phosphor bromophenyl-methyl-pyridinium iodide (PYI) through an electrostatic attraction interaction to form helical microfibers, which display blue fluorescence with circularly polarized luminescence. Moreover, the obtained helical λ-Car@PYI microfibers can be spin-coated into thin films, emitting orange CP-RTP due to the inhibition of RTP quenching in the solid state. Interestingly, further study reveals that the molecular structures and conformation of carrageenans have an important influence on their assembled structures and CP-RTP performance. This study provides a perspective on the design and preparation of CP-RTP materials from natural macromolecules.
