摘要

圆偏振发光（CPL）镧系凝胶虽然具有广泛的应用潜力，但目前很少报道。在这里，我们报道了CPL活性镧系凝胶具有高不对称因子（glum）和59%的高量子产率。本文首次报道了采用简单的低分子量手性凝胶剂制备的左、右手型CPL活性镧系凝胶。此外，还获得了可调谐的CPL信号，包括白光CPL，进一步提升了该材料作为防伪高达4层安全标签的适用性。

Circularly Polarized Luminescent Low Molecular Weight Lanthanide Gels: Tunable Emission Including White Light

Circularly Polarized Luminescent (CPL) lanthanide gels are seldom reported, despite their vast potential for various applications. Here we report CPL active lanthanide gel with a high dissymmetry factor (glum) and a high quantum yield of 59%. This is the first report of both left and right-handed CPL active lanthanide gels by employing simple low molecular weight chiral gelators. Moreover, the tunable CPL signals, including white light-emitting CPL, were obtained, further upgrading the material’s applicability as an anti-counterfeit up to 4-tier security tag.
