E/Z isomerization effects on aggregation-enhanced emission of tetraphenylethene derivatives assisted by host–guest recognition

Pure E and Z stereoisomers of tetraphenylethene derivatives functionalized with dibenzylamine groups were isolated. Both supramolecular polymerization and photophysical changes were more significant in the case of the former than in the latter.

Supramolecular polymerization induced self-assembly into micelle and vesicle via acid–base controlled formation of fluorescence responsive supramolecular hyperbranched polymers

Micellar and vesicular aggregates were achieved in situ by supramolecular polymerization of π-conjugated AB2 monomers with dibenzo-24-crown-8 and dibenzylammonium groups.

Multiple stimuli-responsive supramolecular gels constructed from metal–organic cycles

Two supramolecular networks are constructed from a crown ether based metal–organic cycle and dibenzylammonium based poly(ε-caprolactone)s through multiple host–guest interactions. One of the networks can form organogels at higher concentrations, which show multiple stimuli-responsive behaviors.

Acid–base-controlled and dibenzylammonium-assisted aggregation induced emission enhancement of poly(tetraphenylethene) with an impressive blue shift

The non-covalent interaction between dibenzylammonium chloride and DB24C8 groups in poly(tetraphenylethene)-based conjugated polymers not only leads to an AIEE feature but also a significant blue shift from 515 to 483 nm.

Thermoregulated polyoxometalate-based ionic-liquid gel electrolytes

Thermoregulated POM-type ionic liquid gels show reversible phase transformation, increasing conductivities. And W-containing compounds have higher conductivity than the Mo-containing one, like the Dawson-type one compared with the Keggin-type one.

Fluorescence responsive conjugated poly(tetraphenylethene) and its morphological transition from micelle to vesicle

A crown ether-functionalized poly(tetraphenylethene) (AP-TPE) is synthesized and the rotation of the TPE group is successfully restricted, leading to a stepwise enhanced fluorescence accompanied by a morphological transition from micellar to vesicular.
