TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No preparation method is given. Preferred Components: The redox center comprises a group including arylene bisimides, indolizines, viologens, violenes, and anthraquinones. (I) comprises a 3,4-ethylenedioxythiophene group. Preferred Definitions:    M = thiophene, pyrrole, para phenylene vinylene, furan, carbazole, silole or fluorene; and    R = linear or branched alkylene, glycolic chain, -C(=O)-, -C(=S)-, -O-C(=O)-, -OC(=S)-, -O-C(=O)-O-, -(C=O)-O, -C(=S)-O, -C(=S)-S-, -C(=O)-NR1a- or -C(=S)-NR1a-; and    R1a = H, alkyl, -SO, -SO2, linear or branched alkylic chain or glycolic chain separated by one or more of functional groups.    SPECIFIC COMPOUNDS - 2 Compounds (I) are specifically claimed i.e. pentanedioic acid 2-(1'-(2-(4-(2,3-dihydro-thieno(3,4-b)(1,4)dioxin-2-ylmethoxycarbonyl)-butyryloxy)-ethyl)-2,2'-dimethyl-(3,3')biindolizinyl-1-yl)-ethyl ester 2,3-dihydro-thieno(3,4-b)(1,4)dioxin-2-ylmethyl ester of formula (Ia) and pentanedioic acid 2-(7-(2-(4-(2,3-dihydro-thieno(3,4-b)(1,4)dioxin-2-ylmethoxycarbonyl)-butyryloxy)-ethyl)-1,3,6,8-tetraoxo-3,6,7,8-tetrahydro-1H-benzo(lmn)(3,8)phenanthrolin-2-yl)-ethyl ester 2,3-dihydro-thieno(3,4-b)(1,4)dioxin-2-ylmethyl ester.    EXAMPLE - A mixture of 4.100 g of 2-(2-methylindolizin-1-yl)ethanol and 4.56 g of platinum on carbon in 220 ml of chlorobenzene was stirred at room temperature in an open 500 ml round bottom flask for 24 hours. The mixture was filtered to remove catalyst and washed with chlorobenzene. The filtrate was evaporated under reduced pressure. The residue was purified to obtain clear oil. The residue was triturated with 10 ml of diethyl ether to obtain 901 mg of 2-(3-(1-(2-hydroxyethyl)-2-methyl-indolizin-3-yl)-2-methyl-indolizin-1-yl)ethanol as a pale greenish solid (Q). 13 ml of Acetonitrile was added to a mixture of 350 mg of (Q), 672 mg of 5-(2,3-dihydrothieno(3,4-b)(1,4)dioxin-3-ylmethoxy)-5-oxo-pentanoic acid, 515 mg of N,N'-dicyclohexylcarbodiimide and 27 mg of 4-dimethylaminopyridine under nitrogen atmosphere. The mixture was stirred at room temperature for 4 days, filtered and washed with acetonitrile. The filtrate was collected, evaporated under reduced pressure and purified to give 499 mg of pentanedioic acid 2-(1'-(2-(4-(2,3-dihydro-thieno(3,4-b)(1,4)dioxin-2-ylmethoxycarbonyl)-butyryloxy)-ethyl)-2,2'-dimethyl-(3,3')biindolizinyl-1-yl)-ethyl ester 2,3-dihydro-thieno(3,4-b)(1,4)dioxin-2-ylmethyl ester as a greenish oil.
