Stability of a Conductive State of Poly(3-alkoxythiophene)s
K. Hatakeyama, H. Koizumi,* and T. Ichikawa
[Full Text PDF(J-STAGE)]
 |
Conductive states of poly(3-alkylthiophene)s cause dedoping through deprotonation of polarons resulting in formation of stable polyenyl radicals. In contrast, the deprotonation of polarons of poly(3-alkoxythiophene)s (P3AOT) occurs with difficulty since their deprotonation gives unstable radicals. Conductive states of P3AOT are hence stable.

In mixed-ligand nickel(II) complexes, [Ni(Etx
Me4−x
en)(acac)(NO3)], where acac = acetylacetonate, x = 0–4, the increase of ethyl groups decreases the ligand-field stabilization energy and enhances the ionic dissociation of NO3− in nitromethane solution due to the increase in inter-ligand repulsion.

Exalted Resonance Demands in the Substituent Effects on the Acetolyses of 2-Arylethyl Trifluoromethanesulfonates Destabilized by CN and CF3 Groups
S. Usui,* S. Tsuboya, Y. Umezawa, K. Hazama, and M. Okamura
[Full Text PDF(J-STAGE)]
Extremely large r+
values of 0.98 and 0.93 were obtained in the substituent effect on the acetolyses of 2-aryl-1-cyano-1-(trifluoromethyl)ethyl trifluoromethanesulfonates and 2-aryl-2-cyano-2-(trifluoromethyl)ethyl trifluoromethanesulfonates, respectively. These r+
values suggest strong participation of the β-aryl group in deactivated aryl-assisted solvolyses.
