Controllable Self‐Assembly of Di(p‐methoxylphenyl)Dibenzofulvene into Three Different Emission Forms

Abstract

Self-assembly of di(p-methoxylphenyl)dibenzofulvene in the absence and presence of CTAB (cetyl trimethylammonium bromide) leads to three emission forms: strongly yellow-green- and blue-emissive crystalline forms (as microrods), and weakly orange-emissive amorphous form. Each of these three emission forms can be prepared by adjusting the concentration of CTAB.

Manipulation of the Aggregation and Deaggregation of Tetraphenylethylene and Silole Fluorophores by Amphiphiles: Emission Modulation and Sensing Applications

“…Interestingly, the formation of three emission forms can be controlled with the aid of CTAB (cetyltrimethylammonium bromide). 46 As depicted in Figure 1, the addition of 1 to water led to amorphous solids with weak orange emission in the absence of CTAB. However, in the presence of CTAB with a concentration lower than its CMC, yellow-green emissive microrods were formed.…”

Molecular Design, Circularly Polarized Luminescence, and Helical Self‐Assembly of Chiral Aggregation‐Induced Emission Molecules

“…If more patterns of non‐covalent interactions are constructed by deliberately optimizing the chemical structures of AIE molecules, the self‐assembly process will move towards the desired direction and more judicious self‐assembly architectures will be fabricated with the AIEgens. Thanks to the enthusiastic efforts of scientists, various fluorescent supramolecular architectures, such as micelles, fibers, wires, rods, and ribbons have been constructed by the self‐assembly of AIEgens . Among them, helical micro/nanostructures have drawn much attention owing to their fascinating structures and unique emissive behaviors …”

One platform solid multicolour emission of terthiophene compounds controlled by mixed self-assembly

“…1 shows the optical observations of the precipitates in the 0.10 mM TTC4L system. 34,39 According to our design principle introduced in the previous text, we expect that this should lead to emissions of different colours. In the ratio of 2 : 1, spherical particles of several micrometers are observed, which seem to be hollow under optical microscopy.…”

“…In order to solve this problem, we proposed a strategy of mixed self-assembly in our previous work, 26 which is similar to the formation of self-assembled structures in the oppositely charged surfactant systems. [34][35][36][37] Using this strategy, we have obtained multicolour emissions of the amphiphilic TTC4L in solution simply by tuning the selfassembly of TTC4L with an oppositely charged surfactant DEAB. In case that no specic recognition occurs, the two components will averagely distribute in the mixed self-assembly, 30,32,33 so that the distance between molecules of the same kind is governed by the mixing ratio between the two components.…”
