Separating racemates is still a great challenge for their similarity in chemical structures and physicochemical properties. Despite exhibiting a significant potential in the adsorption separation due to their intrinsic characteristics, hierarchically porous materials utilized in enantioseparation have rarely been reported to date. Furthermore, the molding of such materials together with their hybrid organic-inorganic monoliths is generally required to meet various prerequisites in the diverse large-scale industrial applications, but without sacrificing their inherently hierarchical architectures. In this work, a three-dimensional hierarchically porous organic-inorganic composite was simply and feasibly prepared via integrating the micro/meso-porous hypercrosslinked resin organic polymer (HROP) with macroporous silica gel sheet (SGS), followed by a chiral selector postmodification, named as HROP@SGS. Racemic 1-phenylethanol, ibuprofen and naproxen could be separated only using such a piece of HROP@SGS as the filler with a solid phase extraction technique. Herein, HROP@SGS exhibited extraordinary chiral resolution performances and succeeded in achieving a complete chiral resolution. Our findings suggest that this simple strategy proposed by us, i.e., combining the chiral micro/mesoporous organic materials with macroporous inorganic substrates, can be employed to prepare an unprecedented enantioseparation material, which has a promising potential in large-scale industrial applications, such as fixed-bed and membrane separation.

The statistical manipulation of hierarchically and non-hierarchically nested data. It includes clustered data, such as a sample of subjects within a group of schools. Prevalent in the social, behavioral sciences, and biomedical sciences, both linear and nonlinear regression models are applied.
Polymers of N-SUBSTITUTED GLYCINES containing chiral centers at the a-position of their side chains. These oligomers lack HYDROGEN BONDING donors, preventing formation of the usual intrachain hydrogen bonds but can form helices driven by the steric influence of chiral side chains.
A highly-sensitive (in the picomolar range, which is 10,000-fold more sensitive than conventional electrophoresis) and efficient technique that allows separation of PROTEINS; NUCLEIC ACIDS; and CARBOHYDRATES. (Segen, Dictionary of Modern Medicine, 1992)
The separation of individuals or groups resulting in the lack of or minimizing of social contact and/or communication. This separation may be accomplished by physical separation, by social barriers and by psychological mechanisms. In the latter, there may be interaction but no real communication.
The separation of particles from a suspension by passage through a filter with very fine pores. In ultrafiltration the separation is accomplished by convective transport; in DIALYSIS separation relies instead upon differential diffusion. Ultrafiltration occurs naturally and is a laboratory procedure. Artificial ultrafiltration of the blood is referred to as HEMOFILTRATION or HEMODIAFILTRATION (if combined with HEMODIALYSIS).
