Surfactant-assisted self-assembled polymorphs of AIEgen di(4-propoxyphenyl)dibenzofulvene

Abstract

Diverse morphologies with different emissions can be self-assembled from a single AIEgen (DBF) in the presence of surfactants.

White Light Generation from a Self-Assembled Fluorogen–Surfactant Composite Light Harvesting Platform

“…Surfactants are promising in this context, as they can bring about aggregation of organic molecules, in addition to diluting them. − Amphiphilic surfactants have the ability to self-assemble to produce supramolecular aggregates like micelles, vesicles, and other structures in aqueous solutions, which provide a unique platform for solubilization, aggregation, and self-assembly of hydrophobic organic substances within the hydrophobic core whereas the hydrophilic part imparts stability to the core and retain the ability to be dispersed in aqueous phase. − Therefore, the dimensions and morphologies of the aggregates or self-assembled structures can be easily tailored by adjusting the type and concentration of surfactants. These systems are interesting in the present context, as they are known to be good hosts for organic molecules and form mixed aggregates with them, depending on the relative concentration .…”

Deep insights into polymorphism initiated by exploring multicolor conversion materials

“…For ESI and crystallographic data in CIF or other electronic format see DOI: 10.1039/c9qm00293f same molecular structure, but two or more crystalline phases and shows sharp variations in optical properties. For example, Peng et al 22 gained yellow, green and blue luminous aggregates by changing the types and concentrations of surfactants. Wang et al 23 cultured four crystals of single luminogens with different colors, while Huang et al 10 achieved tricolor crystals by tuning molecular aggregation.…”

Exploration of Highly Efficient Blue–Violet Light Conversion Agents for an Agricultural Film Based on Structure Optimization of Triphenylacrylonitrile

“…By the preparation and doping of crystalline nanoparticles, the PLQY of the PhMe3TPA and Ph4TPA doping film should be sharply improved. Peng et al regulate the packing and arrangement of molecules by surfactants and obtain self-assembled polymorphs . On the basis of this idea, CTAB is selected to optimize the fluorescence emission of TPA in the aggregated state.…”

“…To clarify the internal mechanism, first, the crystal culture and analysis of Ph3TPA obtain self-assembled polymorphs. 21 On the basis of this idea, CTAB is selected to optimize the fluorescence emission of TPA in the aggregated state. Then, enhanced fluorescence emission was observed, but its effect is not significant (Figure S4 of the Supporting Information).…”
