发现一个有趣的新现象：消旋诱导发光增强（原因是AIE，消旋和手性分子排列不一样，导致电荷分布和跃迁不一样）！！！做很多手性发光材料唯此一例。

A series of binuclear cyclometalated Pt(II) complexes with bridge ligand of binaphthyl quinoline were synthesized and characterized. Owing to the restriction of intramolecular motions in chiral binaphthyl linker, the complexes exhibit two unusual metal-induced chiral components and aggregation-induced red phosphorescence. The (R,R,R)/(S,S,S) enantiopure complexes that were confirmed by X-ray diffraction, circular dichroism spectra, time-dependent density functional theory calculations, and circularly polarized luminescence needn’t be purified by chiral high-performance liquid chromatography and can build unique 1D M or P Hierarchical helices of helices via intermolecular noncovalent interactions. Moreover, it is first time to discover racemization-induced phosphorescence enhancement.
