“…The premise of the use of imidazolium‐based podands for the detection of nucleotides is described by Yoon and Kim [22] . Their development is quick [23,24] and gives nowadays birth to novel receptors which are sensitive, selective, and highly bioavailable [25–28] …”

“…nowadays birth to novel receptors which are sensitive, selective, and highly bioavailable. [25][26][27][28] Chen et al [26] have recently reported a new imidazoliumbased receptor (Figure 2) that is GMP-selective in the presence of GDP and GTP but also UMP (uridine monophosphate), TMP (thymine monophosphate) and AMP (adenine monophosphate) in a 100 % aqueous solution and inside of certain mammal living cells. The receptor is of tripodal type, built of three imidazolium rings, each of them bearing a fluorophore (1,8naphthyridine).…”

“…Many bioanion receptors based on this principle have been developed for the detection of nucleic acids and nucleotides in aqueous solution. Tao et al [25] have recently produced a comparative study of several ATP sensors in 100 % aqueous solution (Figure 2). Each of the receptor's two cations bear a tetraphenylethene (TPE) fragment.…”

Luminescent Imidazolium Salts as Bright Multi‐Faceted Tools for Biology

Light and cognate phenomena, e. g., luminescence are powerful tools endowed with great sensitivity to explore the infinitely small. Molecular salts, especially those based on imidazolium units, are granted with original properties and structural versatility. Associated with fluorophores, they constitute highly bioavailable platforms. Their interactions with negatively charged species and biological membranes as well as their controllable cytotoxicity imparted their applications as anion receptors, but also a promising potential as antibacterial and anticancer agents whose mechanism of action can be observed using luminescence, opening the possibility of theranostics (therapy and diagnosis). One of the other assets of imidazolium salts is their flexible amphipathic character which promotes their self‐organizations into liquid‐crystal mesophases and their ability to mimic lipids. Combining luminescence to these amphipathic properties opens new prospects, e. g., following gene or drug delivery inside cells. These salts, all‐in‐one, should lead to new tools for biologists, as well as active theranostic molecules.

Modulation of Imine‐based Aggregation‐Induced Emission Fluorescence Performance Through the Extension of Molecular Linkers

et al. 2022

View full text Add to dashboard Cite

The aggregation-induced emission fluorescent structures based on the imine bonds usually suffer fluorescence quenching owing to the possible charge transfer process between the lone pair electrons from the imine to the fluorescent luminogens. In this work, it was found that the extended molecular linker between the imine units and the TPE core can inhibit the charge transfer process and result in high AIE fluorescent property. A good regularity was found and summarized with a mechanism study. This work may help to solve the problem of the construction of AIE fluorescent structures based on the imine bond.
