PROBLEM TO BE SOLVED: To provide new 4,4'''-dihydroxy-p-quaterphenyls excellent in a liquid crystalline property and capable of improving other properties such as solubility to solvents and to provide a method capable of industrially producing the new compound in high purity and good yield. SOLUTION: The method for producing 4,4'''-dihydroxy-p-quaterphenyls represented by structural formula (1) (R is a methyl group, an ethyl group or a propyl group; n is an integer of 1-3; when R is a methyl group, R<SB>1</SB>is a 1-8C alkyl group and when R is an ethyl group or a propyl group, R<SB>1</SB>is a 1-8C alkyl group and when R is an ethyl group or a propyl group, R<SB>1</SB>is a 1-20C alkyl group) comprises reacting 4,4'''-dihydroxy-p-quaterphenyls represented by structural formula (4) with an alkyl halide represented by structural formula (5) in the presence of an alkali.
