Monomer emission and aggregate emission of an imidazolium macrocycle based on bridged tetraphenylethylene and their quenching by C60

A novel imidazolium macrocycle based on bridged tetraphenylethylene (TPE) was synthesized. Because it bears the bridged TPE units, this macrocycle not only displays an aggregation-induced emission (AIE) effect but also exhibits monomer emission, which is very rare in AIE compounds. With aggregation of the macrocycle, the aggregate emission increases while the monomer emission decreases. It was found that this imidazolium macrocycle can form a stable 2:1 complex with C60, which gives rise to quenching of both the aggregate emission and the monomer emission. Unexpectedly, the aggregate emission exhibited a higher quenching efficiency than the monomer emission, probably because one adsorbed C60 molecule could affect more macrocycle molecules in the aggregate.

Preparation of a fixed-tetraphenylethylene motif bridged ditopic benzo-21-crown-7 and its application for constructing AIE supramolecular polymers

Benzo-21-crown-7 (B21C7) is one of the most important crown ethers, which not only shows excellent physicochemical properties but also exhibits promising binding capability with dialkylammonium salts. In this paper, we designed and synthesized a fixed-tetraphenylethylene (FTPE) motif bridged ditopic benzo-21-crown-7 molecule (H). The fixed tetraphenylethylene motif endows H with aggregation induced emission (AIE) property. In the presence of a ditopic dialkylammonium salt guest molecule (G), a fluorescent supramolecular polymer with golden luminescent property could be fabricated. This B21C7-based host-guest supramolecular polymer with golden fluorescence may have potential application in dynamic luminescent materials.

Preparation method of water-dispersible fluorescent supramolecular polymer nanospheres

The invention discloses a preparation method of water-dispersible fluorescent supramolecular polymer nanospheres, and particularly relates to synthesis based on bridged tetraphenyl ethylene double UPymolecules (denoted as a compound M) and preparation of the fluorescent supramolecular polymer nanosphere under the solubilizing action of a surfactant CTAB. The preparation method has the beneficialeffects that the bridged tetraphenyl ethylene is prepared by using the Suzuki coupling reaction, so that the problems of low yield, high three wastes and the like of the McMurry cross-coupling reaction reported in the previous literature are solved, the synthesis difficulty is greatly reduced, the water-dispersible fluorescent supramolecular polymer nanosphere is formed by self-assembling a monomer M through quadruple hydrogen bonds under the solubilizing action of CTAB, and compared with traditional AIE molecules, the defects that the traditional AIE molecules are subjected to fluorescence quenching in a solution and are difficult to apply to an aqueous solution due to hydrophobicity are overcome. The successful preparation of the water-dispersible fluorescent supramolecular polymer nanospheres provides a reference for the application of fluorescent supramolecular materials.
