Abstract

Abstract : Lipid-encased chiral supramolecular polymer nanorods (SPNRs), synthesized by the nanoprecipitation method in water from a hydrophobic naphthalene-diimide derivative, exhibit excellent thermal stability, intense fluorescence and strong CPL. Abstract : This communication reveals the synthesis of lipid-encased chiral supramolecular polymer nanorods (SPNRs) in water from a hydrophobic naphthalene-diimide derivative by the nanoprecipitation technique. The as-prepared SPNRs exhibit exceptional thermal stability ( T m > 90 °C), excellent photoluminescence ( Φ > 0.5 compared to <0.01 of the monomeric dye) and circularly polarized luminescence with a very high chiral dissymmetry factor ( g lum ) of ∼0.8 × 10 −1 which has rarely been reported for any supramolecular polymer.
