Chiral mesoporous silica (CMS) has attracted widespread attention because of some unique properties, such as high surface area, uniformly structured nanoscale cavities, and excellent chemical and thermal stability. In this work, we report the utilization of a CMS as the stationary phase for the separation of racemates in gas chromatography (GC). A CMS‐coated capillary column was fabricated by a dynamic...
A new enantioselective potentiometric sensor containing R‐type chiral porous organic cage CC9 as the chiral selector was designed for the assay of 2‐aminobutanol. Optimized membrane electrodes displayed a linear dynamic range from 10−3 ~ 10−1 mol·L−1 with a detection limit of 2.5 × 10−4 mol·L−1 and a Nernstian response of 27 ± 0.5mV·decade−1 toward S‐2‐aminobutanol within the pH range 7.0–10.0. The...
Metal–organic frameworks (MOFs) are excellent porous materials with nanoscale cavities and high surface areas, which make them promising as novel adsorbents in solid‐phase extraction (SPE). In this article we report a new application of the chiral MOF [Zn2(D‐Cam)2(4,4′‐bpy)]n in SPE used for the measurement of the enantiomeric excess (ee) of (±)‐1,1′‐bi‐2‐naphthol. Several important experimental parameters...
