An easy ‘Filter-and-Separate’ method for enantioselective separation and chiral sensing of substrates using a biomimetic homochiral polymer

Abstract

We present a polyfluorene appended with protected L-glutamic acid that exhibited a reversible α-helix/β-sheet-like conformation and helical porous fibrous morphology mimicking the super-structure of proteins. The new homochiral polymer probe enabled efficient heterogeneous enantioselective separation and chiral sensing of a wide variety of substrates from their aqueous racemic mixture using an easy ‘Filter-and-Separate’ method.
