Abstract

Abstract : How to convert the weak chiral‐interaction into the macroscopic properties of materials remains a huge challenge. Here, this study develops highly fluorescent, selectively chiral‐responsive liquid quantum dots (liquid QDs) based on the hydrophobic interaction between the chiral chains and the oleic acid‐stabilized QDs, which have been designated as (S)‐1810‐QDs. The fluorescence spectrum and liquidity of thermal control demonstrate the fluorescence properties and the fluidic behavior of (S)‐1810‐QDs in the solvent‐free state. Especially, (S)‐1810‐QDs exhibit a highly chiral‐selective response toward (1R, 2S)‐2‐amino‐1, 2‐diphenyl ethanol. It is anticipated that this study will facilitate the construction of smart chiral fluidic sensors. More importantly, (S)‐1810‐QDs can become an attractive material for chiral separation.
