α-Cyanostilbene and fluorene based bolaamphiphiles: synthesis, self-assembly, and AIEE properties with potential as white-light emissive materials and light-emitting liquid crystal displays

Abstract

Reported bolaamphiphiles self-assembled into triangular honeycomb phases with unique molecular arrangements, and showed the AIEE effect. Their potentials as both WLED and LE-LCD devices have been initially demonstrated.

Phase behaviour of liquid crystalline dendronized fullerene binary mixtures

“…C 60 -4 is synthesized using the same procedure as reported previously. 47 Its chemical structure is characterized by 1 H NMR, 13 C NMR and MALDI-TOF (Fig. S1 and S2, ESI †).…”

“…[1][2][3][4][5][6][7][8] Their self-assembly is normally dominated by the volume fraction of the incompatible moieties, and also affected by many other factors, such as shape and intermolecular interaction. [9][10][11][12][13][14] Controlling the self-assembled structure is important for adjusting chemical or physical properties and adapting the material for various applications. [15][16][17][18][19] A practical and much used method to approach the target performance is using mixtures.…”

Polycyclic Aromatic Hydrocarbon‐based Soft Materials: Applications in Fluorescent Detection, Gelation, AIEE and Mechanochromism

“…Although, fluorene is a member of PAHs, its cyclopentane ring is non‐aromatic in nature [113,114] . Fluorene is nearly planar that enables it to self‐assemble via π‐π stacking, hence, contributes towards the gelation, AIEE and mechanochromism [115,116] . A fluorene ring displays a violet fluorescence; however, its deprotonated form, which is a highly stable aromatic anion (C 13 H 9 − ), shows an intense orange color [117,118] .…”

“…[113,114] Fluorene is nearly planar that enables it to self-assemble via π-π stacking, hence, contributes towards the gelation, AIEE and mechanochromism. [115,116] A fluorene ring displays a violet fluorescence; however, its deprotonated form, which is a highly stable aromatic anion (C 13 H 9 À ), shows an intense orange color. [117,118] Thus, its variable color response can be helpful for the analyte detection.…”

Bis-Pyridine-Based Organogel with AIE Effect and Sensing Performance towards Hg2+

“…In the past thirty years, supramolecular chemistry has become even more sophisticated and quickly developed due to its applications in a variety of disciplines and fields [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. As a typical supramolecular material, low-molecular-weight gels (LMWGs) are a kind of soft material between a solid and liquid which have been developed rapidly and widely used in electrolyte materials [ 12 ], sensors [ 13 , 14 ], drug delivery systems [ 15 ], liquid crystal [ 16 ], supramolecular chirality [ 17 , 18 , 19 ], light-harvesting systems [ 20 , 21 ], surfactants [ 22 ] and other fields [ 23 , 24 , 25 , 26 , 27 , 28 ]. Organic molecules can be self-assembled into organogel or hydrogel under the driving force of noncovalent interactions, such as a hydrogen bond, metal coordination, π–π stacking, hydrophobic effect, electrostatic force and van der Waals force [ 29 , 30 , 31 , 32 , 33 ].…”
