“…Regarding the FT-IR spectrum of MMON-SO 3 H@SO 3 Na (Figure 2c), the intensities of SO peaks located in the range of 1050−1220 cm −1 were significantly enhanced and the typical CC peak at 2250 cm −1 disappeared compared with that of MMON-SO 3 H, which revealed the addition of numerous sulfonate groups onto alkynyl groups within MMON-SO 3 H via the thiol−yne click postmodification. Furthermore, two new bands at 1355 and 2557 cm −1 were regarded as the C−H and S−H bonds' stretching vibrations on MPS, respectively, which further confirmed that the thiol−yne click reaction successfully occurred between the thiol molecules of MPS and alkynyl groups on MMON-SO 3 H. 26,34 Moreover, the EDS and elemental mapping data of MMON-SO 3 H@SO 3 Na confirmed the existence of the Na element and increased the content of the S element from 0.52 to 2.08% compared with that of MMON-SO 3 H (Figure S2), further demonstrating that the −SO 3 Na groups were successfully anchored on the MMON-SO 3 H@SO 3 Na through the thiol− yne click postmodification. The TGA curve showed that the synthesized MMON-SO 3 H@SO 3 Na was stable up to 250 °C (Figure S3).…”

The lack of functional groups or binding sites largely hindered the broad application of microporous organic networks (MONs). Herein, we report the fabrication of the sulfonate group-enriched magnetic MON composite (MMON-SO 3 H@SO 3 Na) via the combination of the sulfonic acid group containing the monomer and thiol−yne click postmodification for efficient magnetic solid-phase extraction (MSPE) of benzimidazole fungicides (BZDs) from complex sample matrices. The welldefined core−shell-structured MMON-SO 3 H@SO 3 Na was obtained and served as an advanced adsorbent for MSPE for concentrating and monitoring trace BZDs. The MMON-SO 3 H@ SO 3 Na with numerous sulfonate groups provides plenty of ion-exchange, hydrogen-bonding, and π−π sites, leading to the favorable affinity to BZDs via multiple interaction mechanisms. The MMON-SO 3 H@SO 3 Na-based MSPE−high-performance liquid chromatography method afforded a wide linear range, low limits of detection, large enrichment factors, good precisions, and reusability for BZDs. Trace BZDs in complex vegetables and fruit samples were successfully detected by the established method. The MMON-SO 3 H@SO 3 Na also exhibited good selectivity toward multiple types of polar contaminants containing hydrogen-bonding sites and aromatic structures. This work provided a new postsynthesis strategy for constructing novel and multifunctioned magnetic MONs for preconcentration of trace analytes in a complex matrix.

“…The synthesized chiral MON-TGC, MON-MSA, and MON-NAC were characterized by solid-state 13 C nuclear magnetic resonance ( 13 C NMR) spectroscopy, transmission electron microscopy (TEM), N 2 adsorption–desorption experiments, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), circular dichroism spectra (CD), water contact angle measurements, and X-ray photoelectron spectroscopy (XPS) (Figures and and Figure S1). The FT-IR adsorption at 830 and 1585 cm –1 correspond to the vibrational stretching of C–H and C–C in pristine MON’s aromatic rings . The characteristic peak at 2200 cm –1 for C≡C reveals the presence of alkynyl groups on MON.…”

Microporous organic networks (MONs) have shown great potential in diverse domains recently. However, the application of MONs in chiral separation or catalysis has been largely lagged due to the lack of chiral MONs and the challenge to synthesize chiral MONs.Here we report a facile thiol-yne click strategy to post-synthesize chiral MONs for the first application in chiral gas chromatography. Three chiral MONs with different chiral centers were rationally designed and synthesized to fabricate their capillary columns for gas chromatographic resolution of various chiral compounds with better resolution than three commercial chiral capillary columns. These results show the great potential of the thiol-yne click strategy for constructing newly chiral MONs and their application in chiral separation.

Covalent Organic Frameworks: Synthesis, Properties and Applications—An Overview

Covalent Organic Frameworks (COFs) are an exciting new class of microporous polymers with unprecedented properties in organic material chemistry. They are generally built from rigid, geometrically defined organic building blocks resulting in robust, covalently bonded crystalline networks that extend in two or three dimensions. By strategically combining monomers with specific structures and properties, synthesized COF materials can be fine-tuned and controlled at the atomic level, with unparalleled precision on intrapore chemical environment; moreover, the unusually high pore accessibility allows for easy post-synthetic pore wall modification after the COF is synthesized. Overall, COFs combine high, permanent porosity and surface area with high thermal and chemical stability, crystallinity and customizability, making them ideal candidates for a myriad of promising new solutions in a vast number of scientific fields, with widely varying applications such as gas adsorption and storage, pollutant removal, degradation and separation, advanced filtration, heterogeneous catalysis, chemical sensing, biomedical applications, energy storage and production and a vast array of optoelectronic solutions. This review attempts to give a brief insight on COF history, the overall strategies and techniques for rational COF synthesis and post-synthetic functionalization, as well as a glance at the exponentially growing field of COF research, summarizing their main properties and introducing the numerous technological and industrial state of the art applications, with noteworthy examples found in the literature.
