“…A conjugated microporous polymer (CMP) is a kind of P-π conjugated polymeric porous material with permanent micropores and a three-dimensional network. − At present, the research on CMPs is widely distributed in the fields of multigas adsorption, − small-molecule gas–liquid separation, , metal catalysis, , photocatalysis, energy storage, , optical sensors − and so on. Compared with traditional molecular sieves and activated carbon, organic porous polymers have the potential to be promising materials for the adsorption of organic dyes through molecular design and functional modification.…”

Water pollution is a serious environmental problem with the rapid development of industry. Organic dyes are an important factor in water pollution. Herein, we design and synthesize a conjugated microporous polymer (CMP) based on triethynylbenzene and dibromohydroquinone (CMP-O) and the quaternary ammonium group-modified product CMP-N. CMP-N shows a low specific surface area of 0.049 cm3/g and low porosity. While CMP-N shows strong dispersity in water, CMP-N exhibits rapid adsorption of anionic dye, especially acid blue 93 (497 mg/g). This research is the first time to provide the alkyl quaternary ammonium group-modified microporous polymer in dye adsorption.

“…In the range of 0.2–200 μM, the absorbance at 652 nm shows a good linear relationship with TC concentration (Figure C), and the detection limit (LOD) is determined as 0.07 μM. Compared with other typical methods − and MIP materials − for TC detection, our method shows a considerable or better performance considering the LOD and detection range (Table S5, Supporting Information). However, in comparison with some recently reported fluorometric methods − and traditional instrumental approaches, the sensitivity obtained by our method is relatively mediocre, which may mainly be limited by the insensitive colorimetric mode.…”

As a typical antibiotic pollutant, tetracycline (TC) is producing increasing threats to the ecosystem and human health, and exploring convenient means for monitoring of TC is needed. Here, we proposed alkali-etched imprinted Mn-based Prussian blue analogues featuring superior oxidase-mimetic activity and precise recognition for the colorimetric sensing of TC. Simply etching Mn-based Prussian blue analogues (Mn-PBAs) with NaOH could expose the sites and surfaces to significantly improve their catalytic activity. Density functional theory calculations were employed to screen the molecularly imprinted polymer (MIP) layer for target identification. Consequently, the designed Mn-PBANaOH@MIP possessed the rich channels for substrates to get in touch with the active Mn-PBANaOH core, showing an excellent catalytic capacity to trigger the chromogenic oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) without the use of H2O2. If TC was introduced, it would be recognized selectively by the MIP shell and masked the channels for TMB access, resulting in the obstruction of the chromogenic reaction. According to this mechanism, selective optical detection of TC was achieved, and performance stability, reusability, and reliability as well as practicability were also verified, promising potential for TC monitoring in complex matrices. Our work not only presents an effective way to enhance the enzyme-like activity of Prussian blue analogues but also provides a facile approach for TC sensing. Additionally, the work will inspire the exploration of molecularly imprinted nanozymes for various applications.

“…In 2017, Zhao and co-workers reported (Scheme ) an ultrathin (2–5 nm) porous organic nanosheet, 82 , in which the phenylene rings in the TPE units are rotatable, thus showing the typical AIE phenomenon. Similarly, Dong et al prepared (Scheme ) the nanosheet 85 , wherein all of the TPE units are connected by phenylene rings. Next, Zhao and co-workers constructed (Scheme ) another 2D π-conjugated C nanosheet, 88 , from monomers 86 and 87 .…”

Dyes exhibiting aggregation-induced emission (AIE) properties can efficiently circumvent the aggregation-caused quenching phenomenon presented in conventional fluorophores in their solid state. As one of the AIE dyes, tetraphenylethylene (TPE) has attracted tremendous attention because of its concise synthesis, stability, at least four reaction sites, and so on, making it a splendid building block for macrocycles and nanocages. In TPE-incorporated macrocycles and nanocages, the AIE effect can be not only preserved but also enhanced as a result of the geometrical constraint of the otherwise rotatable phenylene rings in the TPE units, which endows them with various applications involving the encapsulation and detection of explosives and dyes. This review surveys the recent developments of TPE-incorporated macrocycles and nanocages all the way from the perspective of synthetic strategies involving dynamic covalent chemistry, covalent bonding, and metal coordination to their potential applications in explosives detection, chemical sensing, cell imaging, and catalysis. Finally, we summarize the state-of-the-art status and challenges in this area, which we hope will guide future investigations.
