TEM分析
透過電子顕微鏡(TEM)を使用して、各タイプの材料についての粒径(及び粒度分布)の評価を実施した。各試料タイプについて初期調査画像を一旦得て、より詳細な画像を、粒子カウント及びサイジング用に準備した。
S.C.ジマーマン(S. C. Zimmerman)ら著、「ネイチャー(Nature)」(418巻、399〜403ページ、2002年)及びウェンドランド(Wendland)ら著、「米国化学会誌(J. Am. Chem. Soc.)」(121巻、1389〜1390ページ、1999年)によって詳述されているとおり、8つの内部カルボン酸官能基を含有するコア抜きされたデンドリマーを調製し、特性決定した。コア有機材料は、5,10,15,20−テトラキス(3,5−ジヒドロキシルフェニル)−21H,23H−ポルフィンであった。コア有機材料に結合したデンドロンは、次の構造を有していた。
スズ酸カリウム(3.1ミリグラム)を、2ミリリットルガラスバイアル瓶内の100マイクロリットルの水(スズ酸カリウムが部分的にのみ溶解した)に添加した。本混合物へ、調製例1で調製したコア抜きされたデンドリマー溶液515マイクロリットル(クロロホルム中、0.001モル/リットル)を添加した。本混合物を、16時間、室温で、蓋をしたバイアル瓶内、リストシェーカー上で振盪させた。バイアル瓶の蓋を外し、ゴム隔膜と交換した。二酸化炭素が、本混合物から30分間泡立った。得られた混合物を減圧下で乾燥し、次に引き続いて高真空(66.7Pa(0.5mmHg))にて1時間、室温で乾燥した。2ミリリットルのクロロホルムを乾燥した残留物に添加した。得られた溶液を0.2ミクロンフィルタ(ライフサイエンス社製・GHP ACRODISC、25mm注射器フィルタ、0.2ミクロンGHP膜付き)を通して濾過した。この濾過した溶液の内容物を、TEMによって分析した。図1Aは、実施例1のTEM(倍率X400,000)であり、図1Bは更にデジタル拡大した同一TEMである。コア抜きされたデンドリマー内の酸化スズ粒子は、1.5〜2.0ナノメートルの範囲のサイズを有した。
アルミン酸ナトリウム(4.4ミリグラム)を、500マイクロリットルの水中に溶解させた。100マイクロリットルの本溶液を、2ミリリットルのバイアル瓶に入れた。本混合物へ、調製例1で調製したコア抜きされたデンドリマー溶液515マイクロリットル(クロロホルム中、0.001モル/リットル)を添加した。本混合物を、16時間、室温で、蓋をしたバイアル瓶内、リストシェーカー上で振盪した。バイアル瓶の蓋を外し、ゴム隔膜と交換した。二酸化炭素が、本混合物から30分間泡立った。得られた混合物を減圧下で乾燥し、次に引き続いて高真空(66.7Pa(0.5mmHg))にて1時間、室温で乾燥した。2ミリリットルのクロロホルムを乾燥した残留物に添加した。本溶液を0.2ミクロンフィルタ(ライフサイエンス社製・GHP ACRODISC、25mm注射器フィルタ、0.2ミクロンGHP膜付き)を通して濾過した。この濾過した溶液の内容物を、TEMによって分析した。図2Aは、実施例2のTEM(倍率X400,000)であり、図2Bは更にデジタル拡大した同一TEMである。コア抜きされたデンドリマー内の酸化アルミニウム粒子は、1.5〜2.0ナノメートルの範囲のサイズを有した。
亜鉛イオン溶液は、Zn(NO3)・6H2Oをメタノール中に、0.27モル/リットルの濃度で溶解させることによって調製した。100マイクロリットルの本溶液を、2ミリリットルのバイアル瓶に入れた。本混合物へ、調製例1で調製したコア抜きされたデンドリマー溶液500マイクロリットル(クロロホルム中、0.002モル/リットル)及び50マイクロリットルの1,2,2,6,6−ペンタメチルピペリジン(PMP)を添加した。本混合物は、1時間室温で蓋をしたバイアル瓶内でマグネットスターラにて(magnetically)攪拌した。125マイクロリットルの0.1M・NaOH水溶液をバイアル瓶に添加し、それに続いて混合物を、蓋をしたバイアル瓶を油浴中に吊り下げて40℃で22時間マグネットスターラにて撹拌した。TEM分析によって、粒子が7.3ナノメートルの平均サイズを有することが明らかとなった。倍率X10,000のTEMを図3に示す。
実施例4は、ポリスチレン中に分散された複合粒子を含有するフィルムであった。複合粒子は、実施例3おいて調製されたものであった(コア抜きされたデンドリマー中の酸化亜鉛)。ポリスチレンは、280,000g/モルの重量平均分子量(Mw)を有していた。実施例3の複合粒子とポリスチレンとのクロロホルム溶液は、溶液の質量百分率が、0.6%の複合粒子及び1.5%のポリスチレンであるように調製した。
