摘 要：Low molecular-mass organic gelators（LMOGs） have generated considerable interest during the past decade for the design of smart *** recent years,self-assembly of TTF derivatives through intermolecular interaction leads to gelation of some organic solvents and have been widely investigated for organic conducting materials.[1,2] Herein,we report a series of poly（aryl ether） dendron with an electroactive MPTTFs unit linked through an acyl hydrazone linkage as *** dendrons（1 and 2） could gelate the aromatic solvents and some solvent mixtures,and the subtle change on the molecular structure has a great influence on their gelation *** that the dendrons could form the stable gel in the DMSO/water mixture without thermal treatment and also from the binary gel with [60] fullerene in ***,the gel system exhibited gel-induced enhanced emission（GIEE） property in the visible region in spite of the absence of a conventional fluorophore unit and the fluorescence was quenched by introduction of [60]fullerene.
