A metal-organic supramolecular nanobelt was synthesized by quantitative self-assembling terpyridine-functionized tetraphenylethylene (TPE) and Cd2+, which only showed a weak emission both in solution or aggregated state. Nevertheless, nanobelt

Although photodynamic therapy (PDT) has thrived as a promising treatment, highly active photosensitizers (PSs) and intense light power can cause treatment overdose. However, extra therapeutic response probes make the monitoring process complicated, ex situ and delayed. Now, this challenge is addressed by a self-reporting cationic PS, named TPE-4EP+, with aggregation-induced emission characteristic. The molecule undergoes mitochondria-to-nucleus translocation during apoptosis induced by PDT, thus enabling the in situ real-time monitoring via fluorescence migration. Moreover, by molecular charge engineering, we prove that the in situ translocation of TPE-4EP+ is mainly attributed to the enhanced interaction with DNA imposed by its multivalent positive charge. The ability of PS to provide PDT with real-time diagnosis help control the treatment dose that can avoid excessive phototoxicity and minimize potential side effect. Future development of new generation of PS is envisioned.

A simple synthesis of soluble tetrakis(poly-p-phenylene)ethylenes (TPEs), where poly-p-phenylene units contain up to 4 phenylene moieties, is accomplished using an easily available tetrakis(4-bromophenyl)ethylene and phenyl, biphenyl, and p-terphenylboron
Turn-on fluorescence in a pyridine-decorated tetraphenylethylene: The cooperative effect of coordination-driven rigidification and silver ion induced aggregation
Wang, Ning,Zhang, Junying,Xu, Xing-Dong,Feng, Shengyu
, p. 1883 - 1890 (2020)
A tetrapyridine-decorated tetraphenylethene (TPE) ligand 1 was designed, which, upon interacting with silver ions, displayed "turn-on" fluorescence in a dilute solution. The fluorescence enhancement can be attributed to the cooperative effect of restricti
Aggregation-induced emission encoding supramolecular polymers based on controllable sulfonatocalixarene recognition in aqueous solution
Yao, Xuyang,Ma, Xiang,Tian, He
, p. 5155 - 5160 (2014)
A pH-responsive supramolecular polymer based on a homoditopic bis-p-sulfonatocalixarene host and a tetraphenylethylene derivative guest as building blocks with aggregation-induced emission (AIE) property is fabricated in aqueous solution. Quite different from usual supramolecular polymers constructed before, this novel supramolecular polymer has high luminescence efficiency rather than becoming low-luminescent after polymerization. Interestingly, the AIE signals are switchable between two alternative emission wavelengths in H2O or with ON and OFF switching in the mixing H 2O-THF = 1:1 solution, which are realized by controllable and reversible supramolecular interactions. This strategy to design supramolecular polymers with switchable AIE property overcomes the common problem of aggregation-caused quenching (ACQ) in usual supramolecular polymers and provides a new concept to develop smart supramolecular polymeric materials.
