Redox-switchable polyester dendrimers incorporating both π-donor (tetrathiafulvalene) and π-acceptor (anthraquinone) groups

Bryce, Martin R.,De Miguel, Pilar,Devonport, Wayne

, p. 2565 - 2566 (1998)

The convergent synthesis of (TTF)(x)(AQ)(y) (TTF = tetrathiafulvalene; AQ = anthraquinone) polyester dendrimers is reported; the molecules undergo clean amphoteric redox behaviour with reversible switching between cationic and anionic states being achieve
