Article Abstract

The title compound, C(14)H(10)Br(2)O, is a biphenyl derivative containing a -CH(2)-O-CH(2)- bridge in the 2,2'-position. The compound displays a twisted conformation with the two benzene rings making a dihedral angle of 45.02 (5)°, while the central seven-membered ring is in a boat conformation. The mol-ecule lies on a crystallographic twofold axis of symmetry passing through the O atom and bis-ecting the 1,1' C-C bond.

10,11-Bis[bis(4-dimethylaminophenyl)methylene]dibenzo[bf]thiepin (1) and -oxepin (2) were prepared as stable yellow crystalline compounds, which are the cyclic analogues of electron-donating hexaarylbutadienes. Upon two-electron oxidation, they are reversibly transformed into the title dications (1 and 2 ) exhibiting near-infrared (NIR) absorptions, which were also isolated as stable salts. These redox pairs can serve as new entries into less well-explored organic NIR-electrochromic systems, and the separation of redox peaks (electrochemical bistability) was attained for 1/1 and 2/2 , thanks to drastic geometrical changes between neutral and dicationic states, as revealed by a series of X-ray analyses.
