Abstract:
According to one aspect of the present invention, an organic fluorine compound is represented by a general formula (R-π-E-CH2-A-CH2-E′)n-π′-G (1B) (where n is an integer of 2 to 5, A is a divalent perfluoropolyether group, π is an arylene group or a single bond, R is an alkenyl group or an alkynyl group, and E and E′ are each independently an ether bond or an ester bond or a group that is represented by a chemical formula —O—CH2CH(OH)CH2O— π′ is a group in which n+1 hydrogen atoms are separated from benzene, G is an organic group containing a fullerene skeleton, the n number of groups each of which is represented by a general formula R-π-E-CH2-A-CH2-E′- may be the same or different, and at least one π among the n number of π is an arylene group).
