Abstract: | A novel cyclooctatetraene (COT) radical cation fully annelated with bicyclo2.1.1]hexene units was prepared as SbCl(6)(-) salt, and planarity of the octagonal ring was clarified by ESR and theoretical calculations. Its longest wavelength absorption (630 nm) is blue-shifted from that (745 nm) of COT radical cation annelated with bicyclo2.2.2]octene units due to the widening of the HOMO-SOMO gap accompanying the flattening of the COT ring. structure: see text] |
