Research Progress on Chiral Supramolecular Sensors for Enantiomer Detection

Abstract

Chiral substances occur naturally in abiotic and living systems. The recognition and detection of chiral substances in the natural environment or their analysis and detection in biological systems are crucial. Chiral recognition is a research hotspot in clinical medicine, pharmacology, biochemistry, and other fields. Indeed, many researchers have developed various sensors with different functionalized materials for detecting and analyzing enantiomers. Supramolecular systems have important applications in the development of molecular recognition technologies, and the development of supramolecular chemistry is closely related to research on molecular devices. Therefore, this review summarizes the principle of chiral supramolecular sensors for the detection of enantiomers from the perspective of various sensor types, including optical, electrochemical, electrochemical luminescence, photoelectric, and supramolecular chemical sensors. This review also summarizes the relevant reports on chiral supramolecular sensors in the last five years. Finally, we highlight the prospects of supramolecular chiral sensors in future research.

Preparation of Polyaniline-Modified Cellulose/PDMS Composite Triboelectric Material and Application of Its Pretreatment in MOW Pulp

“…The imine groups in polyaniline (PANI) serve as suitable electron-releasing groups, thereby improving the triboelectric properties of PDMS [19]. Currently, network structures designed through hydrogen bonding [20], supramolecular recognition [21], complexation, electrostatic interaction [22], hydrophobic association [23], and other noncovalent interactions have been developed and applied to strengthen triboelectricity. Therefore, adding fibers can create a uniform network structure, thereby enhancing the mechanical strength of PDMS composites.…”
