D. Sayama, M. Hatanaka, and M. Miyasaka found chiral‐recognition materials based on chitosan resins with switchable optical‐resolution selectivity of D/L‐amino acids. The mechanism of the switchable selectivity was elucidated through the Onsager's reaction field theory. The hydrophilic/hydrophobic properties of the resins determine the selectivity through the permittivity of the comonomers. The cover shows some images of the prototyped chiral‐TLC (thin‐layer chromatography) of D‐ and L‐alanine (left; on chitosan‐HEMA/silica, right; on chitosan‐styrene/silica), dyed by ninhydrin.
