“…Cu-IIPs strategy is particularly interesting and has been summarized in Table 3. 44,83,85,102,[149][150][151][152][153][154][155] From the polymerization technique, solution and bulk polymerization seem to be more favored. Khajeh and his team [149][150][151] have conducted a series of experiments through solution polymerization; for example, Cu-IIPs were prepared with 4-VP as a monomer for extraction, along with Cu(II) analysis via FAAS or ICP-OES, etc.…”

“…However, the utilization of click chemistry in IIPs is relatively rare. Naeimi et al 102 obtained Cu(II)-imprinted mesoporous organosilica nanocomposites as a recyclable catalyst by using click synthesis of 1,2,3-triazole derivatives. Performing related studies is imperative and will further push forward the development of IIPs and click chemistry.…”

“…This method is suitable for analytical chemistry to optimize reaction conditions fast, reasonably, and effectively. With the aid of BBD, Naeimi et al 102 developed a convenient method for one-pot synthesis of b-hydroxy-1,2,3-triazoles over Cu-imprinted periodic mesoporous organosilica nanocomposites (Cu@PMO NCs) under ultrasound irradiation. Thanks to the model, the catalytic synthesis, using water as solvent, ultrasound irradiation, short reaction times and high yields, this work provided an economical and environmentally friendly method, which may be worth additional study.…”

“…Recently, with the aid of unique quenching, catalytic, and solvent effects, some ions can drive research hotspots such as quantum dots and click chemistry related studies. [63][64][65]92,102 (4) In terms of preparation technologies and methods, some boundedness and blindness on the selection of IIPs components still exist. The general polymerization technologies will be continuously used, but related research of combining them with other techniques and materials must be increased for appropriately improving these technologies in order to satisfy higher performance requirements.…”

“…[92][93][94][95] However, reports on click chemistry applied in imprinting are rare. [96][97][98][99][100][101][102] With the aid of Cu(I) catalysis, Li et al 92 have constructed new azo-chromophore-containing hyperbranched polymers (HP1 and HP2) from AB 2 monomers through click chemistry reactions.

Ion imprinting technology (IIT) aims to recognize ions while retaining the unique virtues of molecular imprinting technology (MIT), namely structure predictability, recognition specificity and application universality. Owing to special coordination or electrostatic interactions, ion imprinted polymers (IIPs) are generally compatible with aqueous media and have advantages over most molecularly imprinted polymers (MIPs). IIPs can achieve effective identification of water-soluble ions, especially heavy metals and radioactive elements that cause increasing concerns. The purpose of this review is to summarize recent advances of ion imprinting, focusing on the current status and challenges in fundamentals and applications that involve almost all types of ions and ion-related molecular imprinting. In addition, various smart strategies are highlighted, such as surface imprinting, stimuli-responsive imprinting, dual/ multiple components imprinting, click chemistry, and microwave-assisted heating. In this review, the elemental periodic table is first utilized as a template to introduce ion classification standards for various IIPs, including main groups, transition elements, actinides, rare earths, metalloids, anion imprinting and secondary imprinting. Finally, the challenges and possible solution strategies plus future trends are also proposed (302 references).

Efficient, one pot three-component reaction of alkyl halides, sodium azide with terminal alkynes can be catalyzed by functionalized graphene oxide with copper(I) under thermal conditions. A series of 1,4-disubstituted 1,2,3-triazoles were obtained by this one-pot strategy. The catalyst was prepared and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray (EDX). The catalyst can be reused at least five times without significant deactivation.

In this study, library substituted benzodiazepines was synthesized using molecular ionic liquid supported on Fe‐MCM‐41 nanocomposites (Fe‐MCM‐41‐IL). This protocol using ultrasound provided advantages such as rapid, clean conversion and simplicity in experimental setup that led to rapid generation of benzodiazepines under mild condition. The catalyst can be easily isolated by using an external magnetic field and reused in the next reaction up to six cycles without obvious activity decreasing.
