A compound of the formula (1) R 1 —C 6 H 4 O—CH 2 CH(OH)CH 2 OCH 2 —R 2 —CH 2 —O—CH 2 CH(OH)CH 2 —OC 6 H 4 —R 1 (1) wherein R 1 is alkoxyl having 1 to 4 carbon atoms, amino or amido, R 2 is —CF 2 CF 2 O(CF 2 CF 2 CF 2 O) z CF 2 CF 2 — or —CF 2 CF 2 CF 2 O(CF 2 CF 2 CF 2 CF 2 O) n CF 2 CF 2 CF 2 —, z is a real number of 1 to 15, n is a real number of 0 to 4. 2. A compound as defined in claim 1 wherein z is a real number of 1 to 10. 3. A compound as defined in claim 1 wherein R 2 is —CF 2 CF 2 O(CF 2 CF 2 CF 2 O) z CF 2 CF 2 —, z is a real number of 1 to 15. 4. A compound as defined in claim 1 wherein R 2 is —CF 2 CF 2 CF 2 O(CF 2 CF 2 CF 2 CF 2 O) n CF 2 CF 2 CF 2 —, n is a real number of 0 to 4. 5. A lubricant containing a compound of the formula (1) R 1 —C 6 H 4 O—CH 2 CH(OH)CH 2 OCH 2 —R 2 —CH 2 —O—CH 2 CH(OH)CH 2 —OC 6 H 4 —R 1 (1) wherein R 1 is alkoxyl having 1 to 4 carbon atoms, amino or amido, R 2 is —CF 2 CF 2 O(CF 2 CF 2 CF 2 O) z CF 2 CF 2 — or —CF 2 CF 2 CF 2 O(CF 2 CF 2 CF 2 CF 2 O) n CF 2 CF 2 CF 2 —, z is a real number of 1 to 15, n is a real number of 0 to 4. 6. A lubricant as defined in claim 5 wherein z is a real number of 1 to 10. 7. A magnetic disk comprising at least a recording layer and a protective layer formed over a substrate, and a lubricating layer formed over the resulting surface, the lubricating layer containing a compound of the formula (1) R 1 —C 6 H 4 O—CH 2 CH(OH)CH 2 OCH 2 —R 2 —CH 2 —O—CH 2 CH(OH)CH 2 —OC 6 H 4 —R 1 (1) wherein R 1 is alkoxyl having 1 to 4 carbon atoms, amino or amido, R 2 is —CF 2 CF 2 O(CF 2 CF 2 CF 2 O) z CF 2 CF 2 — or —CF 2 CF 2 CF 2 O(CF 2 CF 2 CF 2 CF 2 O) n CF 2 CF 2 CF 2 —, z is a real number of 1 to 15, n is a real number of 0 to 4. 8. A magnetic disk as defined in claim 7 wherein z is a real number of 1 to 10.
