Anthraquinone-based bolaphile

Anthraquinone-based bolaphile 30 (included in this nonionic section for convenience) was created in order to locate the quinone moiety within the center of a membrane however, stable membrane formation was prevented due to steric considerations. It was possible to integrate this quinoid bolaphile into other host membranes, such as dihexyldecyl-phosphate. The absence of borohydride reduction supports the premise that the quinone functionality is located at the midpoint of the host membrane wall.35 Structures 29, 30, and 31 were synthesized as... 

The anthraquinone-based bolaphile 7 or 8 could not form homogeneous membranes due to steric interactions (Scheme 3) however, they could be integrated into host membranes formed by dihexadecylphosphate and dime-thyldioctadecylammonium bromide. The bolaamphiphile fixed the quinone functionality in the center of the membrane and served as a model for pool quinones. [20] Electron transfer was further demonstrated by light-induced charge transfer between cationic porphyrins dissolved in water and membrane-bound anthraquinone bolaphiles. [27]...
