Abstract A series of poly(aryl ether) dendrons with a monopyrrolo‐tetrathiafulvalene unit linked through an acyl hydrazone linkage were designed and synthesized as low molecular mass organogelators (LMOGs). Two the could gelate aromatic solvents some solvent mixtures, but others not gel all tested except for n ‐pentanol. subtle change on structure produces great influence gelation behavior. Note that form stable in DMSO/water mixture without thermal treatment also binary fullerene (C 60 )...

A series of monopyrrolotetrathiafulvalene–succinamide conjugates and their 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) charge transfer (CT) complexes have been synthesized investigated as new low-molecular mass organogelators. The gelation capability these is highly dependent on the length alkyl chain terminal amide. Thus, only short derivatives 1a 1b could efficiently gelate cyclohexane methylcyclohexane (MCH). Surprisingly, gelators react with TCNQ to form stable CT complex gels in both...

A new monopyrrolotetrathiafulvalene-based derivative containing a urea group was designed, synthesized and thoroughly characterized. It proved to be non-gelator in single solvent even when heated or sonicated. However, it could self-assemble CHCl3 (CH2 Cl2 )/n-hexane mixture form thermo-responsive supramolecular organogel. SEM, FT-IR spectroscopy, UV/Vis absorption SAXS revealed that the organogel system, gelators self-assembled into networks with J-type aggregation mode under joint effect...
