Formula (I) [Chemical 1] Where A represents a C 1-5 -alkylene bridge, R represents a —R 1 — (C═O) —R 2 group, —R 1 — represents —R 3 — or —R 4 —X—R 5 — group. R 2 is hydrogen, a hydroxy group, a thiol group, -NR 6 R 7 , -OR 8 or -SR 9 group, R 3 , R 4 and R 5 are independently an alkylene group or an arylene group, X is —O—, —S— or ═NR 10 , and R 6 and R 7 are independently hydrogen, an optionally substituted amino group or an optionally substituted alkyl group, R 8 and R 9 are independently optionally substituted (optionally substituted with at least one substituent selected from the group consisting of alcohol, amide, ether, ester or sulfonate groups) alkyl Group, optionally substituted A have an aryl group or a -SiR 11 R 12 R 13 group, R 10 is alkyl, aryl or acyl is a group and R 11, R 12 and R 13 are optionally alkoxy substituted or alkyl independently The group, , A polymer derived therefrom, a process for optionally chemically or electrochemically polymerizing the thiophene compound of formula (I), and solutions, dispersions, pastes and polymers containing the polymer derived therefrom layer. |
