TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The reducing agent is lithium aluminum hydride. The chlorinating agent is thionyl chloride.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Producing a fluorous dendron (I) involves reacting phenyl ester compound of formula (II) with olefin compound of formula F-C(F)=C(F)-O-R5 (III) to produce phenyl ester compound (I); reacting the compound (I) with a reducing agent to produce phenyl-methanol compound of formula (IV); reacting the compound (IV) with a chlorinating agent to produce chlorinated phenyl compound of formula (V); and reacting compound (V) with a ester compound of formula (VI) to produce ethyl-benzene compound of formula (VII).R12=1-6C alkyl group;R9, R10 and R11=H or OH;R13, R14 and R15=H or ethyl-benzene compound of formula (VIII).Provided that: at least two of R13, R14 and R15 are (VIII); or at least two of R9, R10 and R11 are OH. Preferred Definitions:    R1=methyl;    R5=perfluoro-n-propyl.    SPECIFIC COMPOUNDS - 4 Compounds are disclosed as compound (I) i.e. 3,4,5-tris(3,4,5-tris-(1,1,2-trifluoro-2-heptafluoropropyloxy-ethoxy)-benzyloxy)-benzoic acid methyl ester (Ia); 3,4-bis(3,4-bis-(1,1,2-trifluoro-2-heptafluoropropyloxy-ethoxy)-benzyloxy)-benzoic acid methyl ester; 3,5-bis(3,4,5-tris-(1,1,2-trifluoro-2-heptafluoropropyloxy-ethoxy)-benzyloxy)-benzoic acid methyl ester; 3,4-bis(3,4,5-tris-(1,1,2-trifluoro-2-heptafluoropropyloxy-ethoxy)-benzyloxy)-benzoic acid methyl ester.    EXAMPLE - A suspension of finely ground dry potassium carbonate (0.7 g) in dry dimethylforamide (25 ml) was added to a three-neck round bottom flask equipped with magnetic stirring, heating bath, condenser, and dropping funnel with pressure-equalization arm and degassed at 50 degrees C for 1 hours, under stirring. Methyl 3,4-dihydroxybenzoate (0.14 g) was added, while purging the system with nitrogen gas. The 3,4,5-PPVE-CH2-Cl (1.65 g) was dissolved in dimethylforamide (15 mL) and added to a dropping funnel and flushed with nitrogen gas for 30 minutes. After work-up, 3,4-bis(3,4,5-tris-(1,1,2-trifluoro-2-heptafluoropropyloxy-ethoxy)-benzyloxy)-benzoic acid methyl ester (1.60 g, yield: 93%) was obtained.
