The electrochemistry recognition of enantiomeric chiral molecules holds great significance for the pharmaceutical industry and scientific research. However, enhancing sensitivity selectivity simultaneously, elucidating mechanism, are two primary challenges. Here, an electrochemical sensor L-C4-PMoV/GO is developed by confining imidazole cations (L-C4) [PMo10V2]5- (PMoV) signal anions within interlayer graphene oxide (GO). highly sensitive to towards drug Levodopa (L-DOPA), which exhibits 16 times higher than L-C4/GO. In addition, enantioselectivity ΔS = 19.92 achieved. Mechanism studies suggest that confinement effect plays a crucial role in synergism between site PMoV L-C4. chiral-confined microenvironment, induction from L-C4 facilitated, results distortion Mo (V)─O bonds. hydrogen-bonding networks among L-C4, (V)─O, DOPA generate adsorption energy difference L/D-DOPA, as revealed situ Raman spectroscopy theoretical calculation. Compared conventional techniques, shows comparable enantiomer excess (ee) value determination, low limits detection (LOD) (6.7 nm L-DOPA, 50.6 D-DOPA), portability, enabling practical recognition.

The development of acid–base catalysts for one-pot cascade reactions remains challenging because the inherent incompatibility inorganic acid and base active sites. Here, we introduced an innovative approach that employs spatial separation to construct separated sites, achieving sequence control reactions. as-prepared bifunctional catalyst applied metal–organic framework (MOF) nanocrystals as separators, with inside microcavities loaded 1 nm polyoxometalate H3PMo12O40 clusters (NENU-5) outside crystal surface covered basic CuCo layered double hydroxide (CuCo–LDH) nanosheets. By applying resultant NENU-5@CuCo–LDH deacetalization–Knoevenagel condensation, over 99% benzaldehyde dimethyl acetal (BDMA) was transformed into final benzylidene cyanoacetate (BCA) a yield at 80 °C solvent-free conditions. Compared random NENU-5+CuCo–LDH, spatially sites indicated higher reaction rate due designed shorter mass transfer pathway. Moreover, this hierarchical structure showed shape selectivity extraordinary stability. This study introduces address issue between offering novel perspectives systems.
