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.

受限的超分子聚合物，在水中具有出色的稳定性，光致发光和手性

这种交流揭示了通过纳米沉淀技术从疏水的萘二酰亚胺衍生物在水中合成脂质包裹的手性超分子聚合物纳米棒（SPNR）。所制备的SPNR具有优异的热稳定性（T _m > 90°C），出色的光致发光（Φ > 0.5，而单体染料的<0.01）和极高的手性不对称因子（g _lum）为的圆偏振发光。 0.8×10 ^-1对于任何超分子聚合物都很少报道。
