(vi) Monovalent Organic Groups Ry’ Having 2 to 20 Carbon Atoms Which Have an Aromatic Ring Structure and at Least One Selected from the Basic Functional Groups Y 1 and/or the Salts Y $^{2 }$of the Basic Functional Groups 

[0110] Concretely the same Ry as mentioned supra can be used preferably, thereby being capable of introducing not less than two Ry to one molecule of the compound of the formula (1) of the present invention and enabling functions of the ionic liquid type functional material to be exhibited more effectively. 

[0111] Preferred examples of Ry’ are the same as the examples of Ry (-A-Ry") raised supra. 

[0112] The aromatic compound of the formula (1) to be used for the ionic liquid type functional material of the present invention is comprised of the fluorine-containing ether moiety -D- to be bonded to the moiety Ry of the aromatic ring structure containing the functional group Y and the residue Ra bonded to another end of -D-, in which to the moiety Ry is bonded at least one -D- (-D-Ra) or may be bonded 2 to 4-D- (-D-Ra) (mis from 2 to 4 in the formula (1 )). 

[0113] Preferred examples of the aromatic compounds of the formula (1) are those obtained in combination of the above-mentioned preferred examples of the fluorine-con› taining ether unit -D-, preferred examples of the moiety Ry having the functional group Y and aromatic ring structure, preferred examples of the bond for bonding D to Ry and preferred examples of the residue Ra. 

[0114] Examples of the aromatic compound of the formula (1) when mis 1 are as follows. 

(1-a) Aromatic Compounds in Which -D- and Ry are Bonded Directly and Ra is a Perfluoroalkyl Group 

[0115] Preferred examples thereof are:
