Functional organogel with α-cyanostilbene scaffold: Aggregation enhanced emission and picric acid sensing

AIE active cyanostilbenes for live-cell imaging of lipid droplets

“…[38][39][40] It has been well established that CF 3 groups and long-chain alkyl groups help to form organogels with higher stability through various non-covalent interactions, packing and bonding interactions. 10,41 We obtained the formation of a stable organogel with compounds bearing two CF 3 groups (N2 and J2) in ethanol upon heating, followed by sonication and cooling. The organogels were found to be stable for 24 h and converted to the sol state upon heating at 100 1C.…”

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

“…Nonetheless, such detections are mainly confined to the phase change from gel to sol in the presence of the analyte. [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] Organogels detecting volatile acids through changes in aggregation induced emission in gel and in film are less often reported in the literature. In this study, an organogelator, APD, containing an acridine moiety linked with a poly(aryl ether) dendron 67,68 through an acylhydrazone 69,70 linkage is designed and synthesized (Chart 1), in the hope that this compound could detect volatile acids through AIE.…”

Functional α-Cyanostilbenes: Sensing to Imaging

“…Due to the alkyl chain and trifluoromethyl groups, the compounds formed stable and thermo-reversible organogels. 38 A stable gel was formed when the molecules had two trifluoromethyl (CF 3 ) groups and showed gelation loss upon adding the picric acid. Sensing of picric acid was also observed in the solution state.…”
