<p>An oligomer or polymer comprising optionally substituted cis-indenofluorene repeating units is new. An oligomer or polymer (P1) comprising optionally substituted cis-indenofluorene repeating units of formula (Ir) is new. [Image] R 1> - R 4>H or a substituent. At least two of R 1> - R 4> may be linked to form a ring. Independent claims are included for the following: (1) an optionally substituted monomer of formula (Im); (2) preparation of (Ir); (3) preparation of optionally substituted 11,12-dihydroindeno [2,1-a] fluorene (A1) involving: eliminating leaving group LG-H from 1,1', 4', 1-terphenyl (substituted by CH 2-LG at positions 2' and 3') (Ip); (4) an optical device comprising (P1); (5) a field effect transistor comprising an insulator having a first and second side; a gate electrode located on the first side of the insulator; (P1) located on the second side of the insulator; and a drain electrode and a source electrode located on the oligomer or polymer; and (6) an integrated circuit comprising the field effect transistor. [Image] R' 1 - R' 4H or a substituent; P : polymerizable group;and LG : leaving group. At least two of R' 1 - R' 4 may be linked to form a ring.</p> |
