TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (I) comprises etherification reaction of a halogen-derivative of formula (X-Ar1(R-Z)-X) (III) with the hydroxyl group of a glycerol derivative of formula (IV) in the presence of a base. Preparation of (II) comprises condensation reaction of (I) with 2 molecules of heteroaryl derivative of formula (Ar2m-W1) (IX) to give a (1,3)dioxolane derivative of formula (IX) followed by halogenation of (IX).Z = Cl, Br or I; andW1 = SnR1a3, -B(OH)2 or -B(OR)2.Preferred Process: In the preparation of (I), the molar ratio of (III):(IV):base is 1:1.1:1.15-1:3:3.3. The preparation of (I) is carried out at a temperature of 15-150 degrees C preferably 20-80 degrees C. In the preparation of (II), the molar ratio of (I):(IX) is 1:2 or 1:4.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The preparation of (II) is carried out at a temperature of 15-200 degrees C, preferably 30-150 degrees C. The polymerization reaction is a condensation reaction, catalyzed by a derivative of a transition metal comprising palladium, in the case of Suzuki, Stille and Heck reactions, or nickel, in the case of a Yamamoto reaction. Preferred Definitions:    Ar1 = group derived from benzene, fluorene, thiophene, carbazole, dithienocyclopentadiene or phenothiazine; and    Ar2 = group derived from thiophene, thieno-thiophene, thiazole, carbazole, dithienocyclopentadiene or phenothiazine.    SPECIFIC COMPOUNDS - 3 Compounds (A) are disclosed i.e. 2,7-dibromo-9,9-bis(3-((2,2-dimethyl-1,3-dioxolan-4-yl)methoxy)propyl)fluorene of formula (AA), 4-(((2,5-dibromo-3-thienyl)methoxy)methyl)-2,2-dimethyl-1,3-dioxolane and 3,6-dibromo-9-(3-((2,2-dimethyl-1,3-di-oxolan-4-yl)methoxy)propyl)-9H-carbazole.    EXAMPLE - Potassium tert-butylate (3 g) was added, in an inert atmosphere, to a solution of solketal (3.5 g) in 1,2-dimethoxyethane (50 ml). After 20 minutes, 2,7-dibromo-9,9-bis(3'-bromopropyl)fluorene (5 g) dissolved in 1,2-dimethoxyethane (15 ml) was added. After 8 hours, after removing 1,2-dimethoxyethane by distillation at reduced pressure, the residue was recovered with ethyl acetate and washed with water until neutrality. After anhydrifying the organic phase on sodium sulfate, the solvent was removed by distillation at reduced pressure and purified to give 2,7-dibromo-9,9-bis(3-((2,2-dimethyl-1,3-dioxolan-4-yl)methoxy)propyl)fluorene (74%).
