“…To sense enantiomers by using POPs, the chiral skeletons are needed because they can provide the chiral porous microenvironment with different binding affinities, which can achieve the chiral discrimination. 216 Li et al synthesized a series of 1,1 0 -bi-2-naphthol (BINOL) based CMPs, CMP1-CMP4, through the Sonogashira-Hagihara coupling reactions (Fig. 28a).…”

“…Zang et al prepared three kinds of chiral conjugated microporous polymer composite membranes with porous silica as the support layer for enantioselective permeation of amino acids in aqueous solution. 867 Homochiral MOF-based membranes have been also reported for chiral separations through enantioselective permeation, 868−870 although the production of high-quality homochiral polycrystalline MOF membranes may present serious difficulties in obtaining by crystallization chiral MOF layers without defects on porous substrates. 871 Alternatively, mixed matrix membranes (MMMs) have been made available in the last few years, which feature the potential advantages of both MOFs and polymers.…”

It is not a coincidence that both chirality and noncovalent interactions are ubiquitous in nature and synthetic molecular systems. Noncovalent interactivity between chiral molecules underlies enantioselective recognition as a fundamental phenomenon regulating life and human activities. Thus, noncovalent interactions represent the narrative thread of a fascinating story which goes across several disciplines of medical, chemical, physical, biological, and other natural sciences. This review has been conceived with the awareness that a modern attitude toward molecular chirality and its consequences needs to be founded on multidisciplinary approaches to disclose the molecular basis of essential enantioselective phenomena in the domain of chemical, physical, and life sciences. With the primary aim of discussing this topic in an integrated way, a comprehensive pool of rational and systematic multidisciplinary information is provided, which concerns the fundamentals of chirality, a description of noncovalent interactions, and their implications in enantioselective processes occurring in different contexts. A specific focus is devoted to enantioselection in chromatography and electromigration techniques because of their unique feature as “multistep” processes. A second motivation for writing this review is to make a clear statement about the state of the art, the tools we have at our disposal, and what is still missing to fully understand the mechanisms underlying enantioselective recognition.

“…As compared to conventional polymers, these polymers possess the advantages of a small electronic bandgap (e.g., 1–3.5 eV), easily modified by the charge transfer process, and having high electrical conductivity [ 117 ]. Hence, conjugate polymers are widely found in many applications, such as solar cells [ 118 ], fuels cells [ 119 ], gas sensing [ 120 ], and particularly the synthesis membranes [ 121 , 122 ]. Their fabrication in hollow fiber configuration remains challenging, while only a handful of research was reported for liquid and gas applications that will be covered in the later section.…”

The aggravation of environmental problems such as water scarcity and air pollution has called upon the need for a sustainable solution globally. Membrane technology, owing to its simplicity, sustainability, and cost-effectiveness, has emerged as one of the favorable technologies for water and air purification. Among all of the membrane configurations, hollow fiber membranes hold promise due to their outstanding packing density and ease of module assembly. Herein, this review systematically outlines the fundamentals of hollow fiber membranes, which comprise the structural analyses and phase inversion mechanism. Furthermore, illustrations of the latest advances in the fabrication of organic, inorganic, and composite hollow fiber membranes are presented. Key findings on the utilization of hollow fiber membranes in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO), pervaporation, gas and vapor separation, membrane distillation, and membrane contactor are also reported. Moreover, the applications in nuclear waste treatment and biomedical fields such as hemodialysis and drug delivery are emphasized. Subsequently, the emerging R&D areas, precisely on green fabrication and modification techniques as well as sustainable materials for hollow fiber membranes, are highlighted. Last but not least, this review offers invigorating perspectives on the future directions for the design of next-generation hollow fiber membranes for various applications. As such, the comprehensive and critical insights gained in this review are anticipated to provide a new research doorway to stimulate the future development and optimization of hollow fiber membranes.
