Smartly designed AIE triazoliums as unique targeting fluorescence tags for sulfonic biomacromolecule recognition: Via 'electrostatic locking'

Specific electrostatic interactions are highly efficient for fluorescent bioassays but they are difficult to achieve. In this work, smartly designed aggregation-induced emission (AIE) triazoliums with donor-acceptor structures were developed via click conjugating a triazole heterocycle onto a tetraphenylethylene (TPE) fluorophore followed by a cationization reaction. The strongly electron-deficient nature of the triazolium coupled with intermolecular electrostatic repulsions resulted in the decrease of TPE's AIE character when it was in solution. However, specific electrostatic locking was found to take place between the triazolium and multiple sulfonates and this unique targeting combination attenuated triazolium's electrophilicity and electrostatic repulsion resulting in the recovery of the AIE. Cryo-electron microscopy (Cryo-EM) was used to reveal the in situ aggregation state of the probe. The triazolium probes exhibited a highly specific turn-on fluorescence response toward sulfonic biomacromolecules such as heparin, chondroitin and sulfonate cyclodextrin, demonstrating that the AIE-triazoliums have great potential for bioassay applications.

Discotic liquid crystals with aggregation-induced emission properties based on tetraphenylethylene and triphenylene derivatives

A novel aggregation-induced emission active molecules (TP-Cn-PETPE, n = 4 and 10) were synthesized, which contain a tetraphenylethene derivative as the emission active moiety, a pentahexyloxytriphenylene core as the mesogenic unit and an alkoxy spacer. Ex

Halogen Bonding Tetraphenylethene Anion Receptors: Anion-Induced Emissive Aggregates and Photoswitchable Recognition

A series of tetraphenylethene (TPE) derivatives functionalized with highly potent electron-deficient perfluoroaryl iodo-triazole halogen bond (XB) donors for anion recognition are reported. 1H NMR titration experiments, fluorescence spectroscopy, dynamic light scattering measurements, TEM imaging and X-ray crystal structure analysis reveal that the tetra-substituted halogen bonding receptor forms luminescent nanoscale aggregates, the formation of which is driven by XB-mediated anion coordination. This anion-coordination-induced aggregation effect serves as a powerful sensory mechanism, capable of luminescence chloride sensing at parts per billion concentration. Furthermore, the doubly substituted geometric isomers act as unprecedented photoswitchable XB donor anion receptors, where the composition of the photostationary state can be modulated by the presence of a coordinating halide anion.
