Efficient Enantiomeric Selectivity Separation Via Homochiral Graphene Oxide Membrane
ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.A new type of chiral graphene oxide (GO) membrane is proposed that exhibits a separation factor of up to 20.1 as well as a preferential enantiomer flux of 4.5 mmol m−2 h−1. Moreover, the only first FPLC‐compatible column has been further developed via stacking these chiral GO membranes.

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.A series of donor‐attached brominated chiral luminescent radicals (CzTTBrM, 2CzTTBrM, and 3CzTTBrM) was synthesized, showing red to near‐infrared (NIR) circularly polarized luminescence (CPL) with exceptionally high PLQY of up to 76% and markedly enhanced CPL brightness (BCPL). Doping into polystyrene microspheres further yields whispering gallery mode

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.Isotelluroureas allow for the use of alkynoates for asymmetric (4+2)‐heterocycloadditions with different Michael acceptors. Alk‐2‐ynoates are readily available starting materials which, in principle, can be utilized for cycloadditions in analogy to structurally similar allenoates.

Mechanochemical Synthesis of Cysteine‐Containing Peptides via Native Chemical Ligation
European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.Cysteine‐containing peptides were efficiently synthesized through mechanochemical native chemical ligation. Cysteine‐containing peptides are important building blocks for the preparation of artificially designed peptides. Therefore, the development of efficient methods for the synthesis of cysteine‐containing peptides is recognized as an important area
