Novel carbosilane liquid crystalline dendrimers based on 1,6‐hexanediol were prepared. Using the precursors G n ‐Cl ( n =1–3) with SiCl bonds on the periphery as dendritic scaffolds and 4‐[4‐(6‐hydroxyhexyloxy)phenylazo]‐nitrobenzene as mesogenic group, a series of carbosilane liquid crystalline dendrimers from the first to the third generation were synthesized. These carbosilane liquid crystalline dendrimers showed smectic phase.
