Preferred Definitions:    X = Cl, I, BF4-, n-BuBF3-, 3,3-dimethylbutyl-BF3-, butylsulfonate, octylsulfonate, perfluorobutylsulfonate, perfluorooctylsulfonate, trifluoroacetate or bis-(2,4,4-trimethylpentyl)phosphinate;    Y1 = N;    R = CF3CF2CF2CF2CH2CH2CH2CH2;    Z = O; and    R1-R3 = C2H5, n-butyl, n-pentyl, n-hexyl, n-octyl, n-decyl or n-dodecyl.    SPECIFIC COMPOUNDS - 51 Compounds (I) are specifically claimed e.g. (11-(4-(5-decyl-pyrimidin-2-yl)-phenoxy)-undecyl)-triethyl-ammonium iodide of formula (Ia), (11-(4-(5-decyl-pyrimidin-2-yl)-phenoxy)-undecyl)-triethyl-ammonium chloride, triethyl-(5-(4-(5-octyloxy-pyrimidin-2-yl)-phenoxy)-pentyl)-ammonium iodide, triethyl-(5-(4-(5-octyloxy-pyrimidin-2-yl)-phenoxy)-pentyl)-ammonium chloride and triethyl-(5-(4-(5-octyl-pyrimidin-2-yl)-phenoxy)-pentyl)-ammonium iodide.    EXAMPLE - 2-(4-(6-Iodo-hexyloxy)-phenyl)-5-octyl-pyrimidine (5.2 g) and tributylamine (19.5 g) were added to a round-bottom flask (100 ml) in toluene (21 ml). The mixture was refluxed at 120 degrees C for 48 hours. The heating and stifling were stopped and the solution was slowly cooled down to room temperature and kept at room temperature overnight. Filtration was carried out and followed by washing with a mixture of hexanes/ethyl acetate to afford a crude product (8 g). The crude product was recrystallized twice from ethyl acetate (100 ml) to afford tributyl-(6-(4-(5-octyl-pyrimidin-2-yl)-phenoxy)-hexyl)-ammonium iodide (6.2 g). Tributyl-(6-(4-(5-octyl-pyrimidin-2-yl)-phenoxy)-hexyl)-ammonium iodide (0.4 g) was dissolved in dichloromethane (100 ml), and potassium perfluorobutylsulfonate (3.98 g) was dissolved in water (150 ml). The dichloromethane solution was extracted with water solution (3x 50 ml) to give an oily product (0.5 g). The oily product was dissolved with hexanes and put in a freezer (-20 degrees C) overnight. Two phases were separated. The top hexane layer was decanted and the bottom oil was dried overnight under vacuum to afford 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonate tributyl-(6-(4-(5-octylpyrimidin-2-yl)phenoxy)hexyl)ammonium (0.42 g).
