Liquid crystallinity of dendronized carbohydrate liquid crystals,which contain carbohydrate core and mesogen branches DOBOB(3,4,5-tris(p-dodecyloxybenzyloxy)benzoic acid),was studied by DSC, thermal polarized optical microscopy,XRD and CD/UV spectrum.The number of branches affects the liq-uid crystallinity significantly.Dendrimer that contains four branches has the highest liquid crystal structure order,and the clearing point is also higher than the other two dendrimers which contain five branches.Oth-erwise,supramolecular chirality is also expressed in the mesophase formed by these dendronized carbohy- drates,which may provide inspiration in searching for chiral mesophase of carbohydrate liquid crystals.

Key words: dendronized carbohydrate liquid crystal, 3,4,5-tris(p-dodecyloxybenzyloxy)benzoic acid, chiral mesophase
