资源简介：
A tetrakis(dialkylamino)phosphonium cation was evaluated
as a functional
group for alkaline anion exchange membranes (AAEMs). The base stability
of [P(N(Me)Cy)4]+ was directly compared to that
of [BnNMe3]+ in 1 M NaOD/CD3OD. The
high base stability of [P(N(Me)Cy)4]+ relative
to [BnNMe3]+ inspired the preparation of AAEM
materials composed of phosphonium units attached to polyethylene.
The AAEMs (hydroxide conductivity of 22 ± 1 mS cm–1 at 22 °C) were prepared using ring-opening metathesis polymerization,
and their stabilities were evaluated in 15 M KOH at 22 °C and
in 1 M KOH at 80 °C.
