Integration of atomically precise clusters into chiral nanoassemblies facilitates the fabrication of functional ordered phases with supramolecular chirality, which remains mysterious. Herein, oxygen-sensitive achiral Cu cluster coassembled with a chiral amphiphile to afford helical nanotube, where Cu cluster was confined within the nanotube to emit phosphorescene, and forming helical arrangement with emerged chiroptical activities including circular dichroism (CD) and circularly polarized phosphorescence (CPP), with a relatively large absorptive asymmetry g-factor up to 0.018. This work offers a facile and universal protocol for designing chiroptical materials based on coinage metal clusters.

非手性铜簇螺旋限制在自组装手性纳米管中，发射圆偏振磷光

将原子精确的簇整合到手性纳米组件中有助于制造具有超分子手性的功能有序相，这仍然是个谜。在此，氧敏感的非手性铜簇与手性两亲物共组装得到螺旋纳米管，其中铜簇被限制在纳米管内以发射磷光，并形成具有圆二色性（CD）和圆偏振磷光（CPP）等手性活性的螺旋排列。 )，具有相对较大的吸收不对称性g因子高达 0.018。这项工作为设计基于造币金属簇的手性光学材料提供了一种简便且通用的协议。
