Nitro-Stabilized Proton Abstraction Doped Model Compounds as Precursors to Conducting Polymers.

Pagination or Media Count:
Conducting polymers have received extensive attention recently, but a few traditional problems such as the need for toxic dopants, material intractabilities, and poor environmental and oxidative stabilities still exist that severely plague the field. Although most work on solving these problems has been based on electron transfer as a doping mechanism, we have defined a new mechanism based on Proton Abstraction Dopind PAD, which has eliminated many of the above problems but has created several of its own. Our previous work has centered on abstraction of doubly benzylic andor allylic protons with strong base, but both the use of strong base and the resulting reactive anion make this a difficult system to handle in the air. Preliminary results show that the incorporation of electron withdrawing nitro groups into these materials seems to overcome this problem.
