Description
で表される。上記の構造から分かるように、ポリマー骨格は、1〜20個の炭素を有する直鎖状の有機基を介してスルホニル基に連結され得る。複素環基(この場合にはイミダゾール)が、スルホニル基に結合され、スルホニル基に対して外側に立体的に配置されている。
で表される。上記の式のように、今度はポリマー骨格が、示されているイミダゾールを含む複素環化合物に連結されている。複素環化合物は、複素環化合物に対して外側に立体的に配置されたスルホニル基に結合されている。
2−エチルスルホニル−イミダゾールの電気化学的安定性
図1を参照すると、窒素でパージした、2−エチルスルホニル−イミダゾールおよびイミダゾールのCH3CN溶液のサイクリックボルタモグラムが示されている。白金の作用電極および白金の補助電極ならびに0.1mol・dm-3のTBAPF6を含有する0.1mol・dm-3のAgNO3−CH3CNを有する銀Ag/Ag+の基準電極を用いて、テトラブチルアンモニウムヘキサフルオロホスフェート(TBAPF6)および5×10-3mol・dm-3のイミダゾールまたは2−エチルスルホニル−イミダゾールのCH3CN溶液0.1mol・dm-3を有する3つの電極セルにおいて、サイクリックボルタンメトリー測定を行った。図から分かるように、イミダゾールのボルタモグラムにおいて、1.0ボルト付近で大きな酸化ピークが現れた。イミダゾールの酸化生成物が白金電極の表面に吸収され、それによって電極の表面領域をブロックしていることが分かった。一方、2−エチルスルホニル−イミダゾールについては、基準電極に対してより広い電位範囲(0〜1.8ボルト)において酸化還元ピークが見られなかった。50サイクル試験中、変化は起こらなかった。50サイクルの後、2−エチルスルホニル−イミダゾールを含む溶液にイミダゾールを加えると、大きな酸化ピークが現れた。同様の結果が、CH3CN溶液をO2でパージしたときにも見られた。このことは、2−エチルスルホニル−イミダゾールが、燃料電池条件下で改良された電気化学的安定性を有することを示唆している。
2−エチルスルホニル−イミダゾールとベンゼンスルホン酸との混合物
以下の方法を用いて2−エチルスルホニル−イミダゾールを調製した。2−メルカプトイミダゾールを、アルカリ性水溶液中でハロゲン化アルキルと反応させて、2−アルキルチオイミダゾールを調製する。次に、2−アルキルチオイミダゾールを、通常の酸化剤を用いて酸化させて、2−アルキルイミダゾールを生成する。
