A novel aryl compound represented by the formula (1) in which the characteristic groups represented by X1 and X2 are different from each other: wherein X1 and X2 are characteristic groups which are different from each other and each of which is selected from the group consisting of a chlorine, bromine or iodine atom, -OSO2Q1, -B(OQ2)2, -Si(OQ3)3, -Sn(Q4)3, Z1 (Z2)m, a metal acetylide group and a terminal acetylene group (where Q represents a hydrocarbon group; Q2 represents a hydrogen atom or a hydrocarbon group; two Q2's may be the same as or different from each other or may together form a ring; Q3 represents a hydrocarbon group and three Q3's may be the same as or different from one another; Q4 represents a hydrocarbon group and three Q4's may be the same as different from one another; Z1 represents a metal atom or a metal ion; Z2 represents a counter anion; and m is an integer of 0 or higher); Ar1 and Ar2 independently represent an arylene group and Ar3 represetns an aryl group, provided that any two of Ar1, Ar2 and Ar3 may be bound to each other via a substituent or directly; Y represents a trivalent atomic group having a nitrogen, carbon, boron or silicon atom to which a hydrogen atom or a hydrocarbon group may be added if required; J represents an arylene group; and n is an integer of 0 or higher; provided that, when each of J, Y and Ar3 is present in the molecule in plural number, they may be the same as or different from each other or one another.
