Ditopic helicate ligands and were synthesized for the formation of dinuclear Eu luminescent chiral helical assemblies (Eu·L) in competitive organic and protic solvent media. Spectroscopic analysis revealed formation of the 2:3 (Eu·L) and 2:2 (Eu·L) species in methanolic solutions. Circular dichroism and circularly polarized luminescence (CPL) spectroscopy confirmed the chiral purity of the helical systems, while scanning electron microscopy imaging demonstrated the formation of hierarchical self-assemblies with spherical morphologies.
为了在竞争的有机和质子溶剂介质中形成双核 Eu 发光手性螺旋组装体(Eu·L)，合成了双位穴状配体 和 。光谱分析表明在甲醇溶液中形成了 2:3(Eu·L)和 2:2(Eu·L)物种。圆二色性和圆偏振发光(CPL)光谱证实了螺旋体系的手性纯度，而扫描电子显微镜成像则证明了具有球形形态的分级自组装的形成。
