PROBLEM TO BE SOLVED: To obtain a hydrophobic compound effective for the orientation control of liquid crystalline molecules. SOLUTION: This hydrophobic compound with excluded volume effect is obtained by binding hydrophobic groups and cyclic groups to each other as shown by the formula (I): (Hb-L1-Cy1-L2-)nCy2 (wherein, Hb is a 6-40C aliphatic group or 6-40C aliphatic-substituted siloxanoxy group; L1 is a single bond, alkylene, fluorine-substituted alkylene, O, S, CO, NR, SO2 or a combination thereof; Cy1 is a bivalent aromatic group or bivalent heterocyclic group; L2 is a single bond, alkylene, alkenylene, alkynylene, O, S, CO, NR, SO2 or a combination thereof; n is 2, 3 or 4; and Cy2 is an n-valent aromatic group or n-valent heterocyclic group). |
