Recently, scientists have reported a range of chiral fluorescence materials or chiral composites that can emit circularly polarized luminescence. Herein, two achiral metal-organic colloidal solutions were studied, showing active circularly polarized luminescence, which is observed in vortex stirring. The absolute values for g are 0.05 and 0.03 and the plus or minus sign of g depends on the colloidal structure and stirring direction, which make the property easy to manipulate. Further, the host-guest interaction study suggests both electrostatic interactions and coordination bonding may influence the chiroptical property from the colloidal solution to the guest molecule. Rhodamine 6G and its carboxylic acid derivative exhibit good quantum yields and acceptable g values in the colloidal solution.
最近，科学家们报道了一系列能够发射圆偏振光的手性荧光材料或手性复合材料。在此，研究了两种非手性金属有机胶体溶液，它们在涡旋搅拌中表现出活性圆偏振发光。g的绝对值分别为0.05和0.03，g的正负号取决于胶体结构和搅拌方向，这使得该性质易于调控。此外，主客体相互作用研究表明，静电相互作用和配位键合都可能影响从胶体溶液到客体分子的手性光学性质。罗丹明6G及其羧酸衍生物在胶体溶液中表现出良好的量子产率和可接受的g值。
