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　glum　are　0.05　and　0.03　and　the　plus　or　minus　sign　of　glum　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　glum　values　in　the　colloidal　solution.　©　2021　Wiley-VCH　GmbH
