HCID 21871601, compound → 3,4-Ethylenedioxythiophene

Temperature

80 °C

PEGdTh (400) (0.64 mmol) was dissolved in n-butanol (0.5 ml), mixed with 32.4 g of Baytron® C from Bayer (50% wt. Fe(pTS)3 in butanol, =23 mmol of iron), and heated under stirring to 80° C. Freshly distilled ethylenedioxythiophene (EDOT from Bayer; 1.6 g=11.3 mmol) was dissolved in 120 ml of n-butanol (final concentration of 10−2 M) and slowly added to the hot mixture of PEGdTh and Baytron® C over a 1.5 hr period under stirring. After the addition was completed, the reaction was kept at 80° C. for 1.5 hr, then cooled to room temperature and stored overnight. The following day the solution was dark blue and no precipitate was present.
