Versatile robust organogels based on a low molecular weight gelator of phenylquinolinylacrylonitrile

Abstract

Herein, we have synthesized three new phenylquinolinylacrylonitrile derivatives. It is found that ((Z)-2-phenyl-3-(quinolin-4-yl)acrylonitrile) (1) and ((Z)-2-(4-fluorophenyl)-3-(quinolin-4-yl)acrylonitrile) (2) can form organogels in polar solvents, and compound 2 shows good gelation ability...

Polymorphism manipulating topo-photochemical reactions, photoactuation, and the mechanofluorochromism of benzimidazoleylaryl acrylonitriles

“…It is well known that α-cyanostilbenes exhibit good self-assembling ability and aggregation-induced emission behaviors, 37 and have potential applications in chemosensors, organic light-emitting diodes (OLED) or biological imaging devices. 38 Besides, α-cyanostilbenes can undergo photoisomerization, 37 [2+2] cycloaddition 39 and electrocyclic reactions 40 in the solid states. Li et al reported that the position of the CN group in α-cyanostilbenes has a great influence on the electronic structures, intermolecular interactions, packing modes and photophysical properties.…”

Aggregation induced emission and volatile acid vapour sensing in acridine appended poly (aryl ether) based low molecular weight organogelator

“…24–42 Organogels detecting volatile acids through changes in aggregation induced emission in gel and in film are less often reported in the literature. 43–66…”

Self-Assembly of a Series of Carbazole-Based Vinyl-benzoxazole Derivatives in Gel Phases

“…Supramolecular gels formed by low-molecular-weight gelators have recently attracted considerable attention because of their numerous practical applications, such as photovoltaics, – field-effect transistors, oil or dye absorption, , drug release, , medical treatment, , and various sensors for gases, – cation, – anion, neutral molecules, and light . These supramolecular gels are composed of a large number of solvents and a small amount of gelator.…”
