New chalcones containing carbazole and 3,4-ethylenedioxythiophene fragments

Acylation of 9-(2-ethylhexyl)carbazole with acetyl bromide in the presence of tin(IV) chloride gave 3-acetyl- and 3,6-diacetyl-9-(2-ethylhexyl)carbazoles which were brought into condensation with 3,4-ethylenedioxythiophene-2-carbaldehyde to obtain new chalcones capable of undergoing electrochemical and chemical polymerization.
